HELYX-Core is a heavily modified version of the standard OPENFOAM®1 library developed and maintained by ENGYS.

1. Version Current HELYX-Core software release version 3.1.1.

The current HELYX-Core release is based on a Q4 2017 version of OPENFOAM.

2. Software Enhancements The following utilities and solvers in HELYX-Core have been implemented or improved by ENGYS in the public OPENFOAM® release:

HELYX® 3.1.1 | Release date 13/11/2018

New Features 1. Added new layer growth method "rfch" to helyxHexMesh (Supported in both dual and

standard version) which inputs the first cell height relative to the local mesh spacing. $FOAM_SRC/mesh/snappyHexMesh/layerManipulate/layerManipulate.C $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver/layerParameters/layerParameters.C $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver/snappyLayerDriver.C

14. Changed default enthalpy solvers to smoothSolver from GAMG (which was causing stability issues with helyxCHT on some cases). $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/helyxCHTBase.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/helyxCHTTransientBase.cfg

15. Perform sync of points in enlarged face-point stencil to prevent the reversal mechanism in helyxHexMesh leaving error cells. $FOAM_SRC/dynamicMesh/motionSmoother/motionSmootherAlgo.C

16. Fixed a bug un wallHTC. For ico case, rhoCp is now used instead of rho. This is due to the fact that alphaEff is not divided by rho in the solver. $FOAM_APP/utilities/postProcessing/wall/wallHTC/wallHTC.C

17. Made changes to the relaxation factors for the T-equation in buoyantBoussinesqP/Simple solvers. This was because of issues with a case which was converging badly with the previous default values. $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/buoyantBousinesqPimpleFoamRAS.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/buoyantBousinesqSimpleFoam.cfg

27. Addressed issue related to non-linear Cp functions. The original coupledWallEnergy assumes implicitly that ethalpy = Cp*T. coupledWallEnergy was modified to provide h/T as weight instead of Cp. This is effectively a linearisation of Cp. $FOAM_SRC/regionCoupled/derivedFvPatchFields/coupledWallEnergy $FOAM_SRC/thermophysicalModels/basic/rhoThermo/rhoThermos.C $FOAM_SRC/thermophysicalModels/specie/thermo/hPolynomial

28. Updated rhoPorousSimpleFoam to deal with radiation constructor in createFields. Added support for radiation environment in rhoPorousSimpleFoam. Note, the solver itself does not support radiation. This is not a new feature, but rather a workaround to cope with the changes to rhoSimpleFoam postprocessing. $FOAM_APP/solvers/compressible/rhoSimpleFoam/rhoPorousSimpleFoam/Make/options $FOAM_APP/solvers/compressible/rhoSimpleFoam/rhoPorousSimpleFoam/rhoPorousSimpleFoam.C

2. Added new interface capturing capability for multiphase VOF cases through the isoAdvector algorithm currently available in the interIsoFoam solver (OpenFOAM 1706). $FOAM_SRC/finiteVolume/fvMatrices/solvers/isoAdvector $FOAM_APP/solvers/multiphase/interIsoFoam

3. Added a new lumpedPointMotion library that makes it possible to perform FSI on lumped point models (OpenFOAM 1706). $FOAM_APP/utilities/postProcessing/lumped $FOAM_TUT/incompressible/lumpedPointMotion/building

4. Added new low Mach number acoustic modelling solver (OpenFOAM 1706). $FOAM_APP/solvers/compressible/rhoPimpleAdiabaticFoam $FOAM_TUT/compressible/rhoPimpleAdiabaticFoam/rutlandVortex2D



5. Added new jouleHeating fvOption that allows the use to add joule heating capability to any thermal solver (OpenFOAM 1706). $FOAM_SRC/fvOptions/sources/derived/jouleHeatingSource $FOAM_TUT/heatTransfer/chtMultiRegionSimpleFoam/jouleHeatingSolid

6. Added setTimeStep function object that allows for smoother time step control (OpenFOAM 1706). $FOAM_SRC/functionObjects/utilities/setTimeStep $FOAM_SRC/OpenFOAM/db/functionObjects/timeControl

7. Added new wave generation models Grimshaw and McCowan (OpenFOAM 1706). $FOAM_SRC/waveModels $FOAM_TUT/multiphase/interFoam/laminar/waveExampleSolitaryGrimshaw $FOAM_TUT/multiphase/interFoam/laminar/waveExampleSolitaryMcCowan

8. Added new Curle function object that calculates acoustic pressure based on the Curle acoustic analogy (OpenFOAM 1706). $FOAM_SRC/functionObjects/field/Curle $FOAM_TUT/incompressible/pimpleFoam/LES/vortexShed

9. New wall-bounded streamline calculation algorithm has been added to make it possible to calculate the streamline paths along boundary faces of inverted cells (OpenFOAM 1706). $FOAM_SRC/functionObjects/field/wallBoundedStreamLine

10. Created a dual mesh generator for HELYX. $FOAM_SRC/mesh/autoMesh/autoHexMesh

11. Added time dependent ambient temperature to boundaryRadiationProperties (Function1 input format). Changed identifier from Tinf to Ta (<- ambient) for consistency sake. Tinf is still supported for backward compatibility. $FOAM_SRC/thermophysicalModels/radiation/submodels/boundaryRadiationProperties

12. Added a tutorial that provides a good example on how to set up an external flow AEC case. It utilises the windProfileVelocity and associated boundaries and also showcases the new implementation of interpolatedInletOutlet. Further, this case uses SIMPLEC and other improved best practices. (switch to leastSquares for gradients, relaxation factors for SIMPLEC). $FOAM_TUT/incompressible/simpleFoam/cylindricalDomainWind

13. Added blood flow boundaries provided by Vascularflow to HELYX-core. Add lumped resistance outlet pressure boundary "flowRateResistancePressure" and pulsitile flow rate boundary "flowRateTubeVelocityProfile". Also, added supporting interpolation scheme for "mass conservative interpolation" for Rhie-Chow. $FOAM_SRC/TurbulenceModels/incompressible/turbulentTransportModels/derivedFvPatchFields/groupOfHumansHeatFlux $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/flowRateResistancePressure $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/flowRateTubeVelocityProfile $FOAM_SRC/OpenFOAM/fields/Fields/tensorField/tensorField.C

14. Added new initialisation method "Laplace". Generates a smooth field from boundary conditions. Useful for initialising compressible flows with pressure-pressure boundaries. Input: "alpha <diffusion coefficient>; nNonOrthogonalCorrectors <#>; coefficientFieldName <word>; (for boundaries that need the rAU scalar field). Currently, the Laplace initialisation is only allowed for pressure fields. Add Laplace to "allowedInitialisationMethods" for other fields to enable. $FOAM_APP/utilities/preProcessing/caseSetup/stateFunctions/fieldInitialisation/Laplace $FOAM_ETC/caseDicts/preProcessing/caseSetup/fields/pressure.cfg

15. Added "reuseExistingDictionaries" switch back into caseSetup. This switch can be added to the "modificationSwitches" section. The default is false. This can be used (for example) with a null state to initialise fields for post-processing applications, without mangling existing settings. $FOAM_APP/utilities/preProcessing/caseSetup/stateFunctions

16. For decoupledEulerian, added report for fluxes at patches. This is done directly into the solverObject, which now can output for each patch 1) global values in [Kg] or [Kg/s] in the .log file 2) Fields in [Kg/m2] or [Kg/m2 s]. By means of a switch, the user can chose to sum over the time the fluxes (the startTime can be set). $FOAM_SRC/solverObjects/solvers/decoupledEulerianSpray

17. Add caseSetup state for eulerian post-processing application which allows the user to leave state empty or only add modules. $FOAM_APP/utilities/preProcessing/caseSetup/stateFunctions $FOAM_ETC/caseDicts/preProcessing/caseSetup/caseSetup.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/fields/coupled.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/fields/velocity.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/functions/functions.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/solvers.cfg

18. Generalised the velocityGradientDissipationInletOutlet boundary. Extended the coupling between velocity gradient and turbulent dissipation in converged flow scenarios. Added support for omega, limit maximum length scale. This boundary can only be used with windProfileDirectionVelocity. Example usage in new tutorial simpleFoam/cylindricalDomainWind. Added new keyword "Lmax" to specify maximum length scale. Prevents issues where input gradient is zero. Boundary can now be used with omega as well as epsilon (nuTilda won’t work as k is required). $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/velocityGradientDissipationInletOutlet

19. Added skinFriction calculation in fieldProcess.



$FOAM_SRC/postProcessing/functionObjects/field/fieldProcess 20. Added reporting of layer information in new dual mesher.

$FOAM_APP/utilities/mesh/generation/helyxHexMesh/helyxHexMesh.C $FOAM_SRC/mesh/snappyHexMesh/addHexMeshLayers/addMultiLayers.C $FOAM_SRC/mesh/snappyHexMesh/layerManipulate

21. Added to helyxHexMesh an edge length mesh quality check. The keyword is called minEdgeLength and currently set as default to -1 (disable check). $FOAM_ETC/caseDicts/mesh/generation/helyxHexMeshDict.cfg $FOAM_ETC/caseDicts/mesh/generation/meshQualityDict.cfg $FOAM_SRC/dynamicMesh/motionSmoother/motionSmootherAlgoCheck.C $FOAM_SRC/dynamicMesh/motionSmoother/polyMeshGeometry $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver/snappySnapDriver.C

22. Implemented smoke/soot visibility index as functionObject. $FOAM_SRC/functionObjects/field/visibilityIndex

23. Added optional list of paths to search for triSurfaces in helyxHexMeshDict if it cannot find surface in constant/triSurface. To activate this feature, add "alternativeSurfacePath ("PATH/TO/SURFACE/GLOBAL" "PATH/TO/SURFACE/LOCAL");" to top level helyxHexMeshDict. $FOAM_APP/utilities/mesh/generation/helyxHexMesh/helyxHexMesh.C $FOAM_src/meshTools/searchableSurface

24. Added simple calculator which takes as input any three of the following to calculate all layer parameters: numLayers, expansionRatio, firstLayerThickness, finalLayerThickness and totalLayerThickness. $FOAM_APP/utilities/mesh/manipulation/layerCalculator

25. Added keyword smoothBaffleEdgeNormals to layer controls (Default: false) to aid growing layers around around baffle edges. By not smoothing baffle points, normals are fixed during patch point normal smoothing. $FOAM_SRC/mesh/snappyHexMesh/externalDisplacementMeshMover/medialAxisMeshMover.C

26. Added ability to remove cells at end of mesh refinement by using topoSet interface. $FOAM_SRC/mesh/snappyHexMesh/addHexMeshLayers/addHexMeshLayer.C $FOAM_SRC/mesh/snappyHexMesh/meshRefinement $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver

27. In caseSetup configuration, added support for blockKOmegaSSTawtDES and blockKOmegaSSTawtDDES incomressible LES turbulence models. $FOAM_ETC/caseDicts/preProcessing/caseSetup/models/turbulence.cfg

28. Added sensorControlledFixedValue boundary condition. $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/sensorControlledFixedValue



29. Added ability for baffle patches to grow layers only in the surface normal direction. This is achieved by adding keyword singleSided (at same level as nSurfaceLayers keyword) and setting its value to true. $FOAM_APP/utilities/mesh/generation/helyxHexMesh/helyxHexMesh.C $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver

30. Extend fluidHeight function objects so it supports cellSets. $FOAM_SRC/postProcessing/functionObjects/report/fluidHeight

31. Added flux-directed weighting and output weighting flux to enable post-processing of phasic flow rates. $FOAM_SRC/postProcessing/functionObjects/report/surfaceReport

32. Added multi-criterion refinement for increased usability and flexibility of adaptive mesh refinement. $FOAM_SRC/dynamicFvMesh/dynamicMultiCriterionRefineFvMesh

33. Added keyword moveCentroidsTol to castellatedMeshControls which can be set globally or on a per surface basis. When a cell centre is closer to the surface than the tolerance the cell centre is moved for intersection checks. The default value is -1 which deactivates this feature. $FOAM_SRC/mesh/snappyHexMesh/meshRefinement $FOAM_SRC/mesh/snappyHexMesh/refinementSurfaces

34. Added new Foam to Abaqus exporter. Support for .inp read and write. Can read NODEs and ELEMENTs tria S3 and quad S4. Also added new mapFoamToSurface application for mapping from OF to surface using AMI interpolation. $FOAM_APP/utilities/postProcessing/dataConversion/mapFoamToSurface $FOAM_APP/utilities/postProcessing/dataConversion/foamToAbaqusSurfaceMap $FOAM_SRC/triSurface/triSurface/interfaces/INP

Bugs Fixed / Maintenance 1. Improved stability and readability of output for helyxCHT by adding cellLimited to solid region

enthalpy gradient; accounting for zero overlaps in coupledWallEnergy patch-to-patch interpolation; adding a relaxation factor for radiation source term (keyword for radiation relaxation factor is "Qurf"); inserting spacer to distinguish time steps in top level helyxCHT output. $FOAM_APP/solvers/heatTransfer/helyxCHT/helyxCHT.C $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/helyxCHTSolid.cfg $FOAM_SRC/OpenFOAM/db/functionObjects/timeControl/timeControl.C $FOAM_SRC/regionCoupled/derivedFvPatchFields/coupledWallEnergy/coupledWallEnergyFvPatchScalarField

2. Multiple updates to function objects, for caseSetup and backward compatibility. $FOAM_ETC/caseDicts/preProcessing/caseSetup/functions/functions.cfg $FOAM_SRC/fileFormats/ensight/file/ensightGeoFile.C $FOAM_SRC/functionObjects/utilities/ensightWrite/ensightWrite.C



$FOAM_SRC/functionObjects/utilities/heatBalance 3. Updates to fieldProcess to remove calculationControl keyword and allow backward

compatibility support. $FOAM_SRC/OpenFOAM/db/functionObjects/timeControl/timeControl.C $FOAM_SRC/functionObjects/field/fieldProcess $FOAM_SRC/functionObjects/forces/liftDrag/liftDrag.C $FOAM_SRC/functionObjects/report/volumeReport/volumeReport.C

4. Reverting PointEdgeWave class to original version. This improves layer generation performance on high core counts. $FOAM_src/mesh/snappyHexMesh/externalDisplacementMeshMover/medialAxisMeshMover.C $FOAM_SRC/mesh/snappyHexMesh/layerManipulate/layerManipulate.C $FOAM_SRC/meshTools/algorithms/PointEdgeWave

5. Fixes issues with pre-balancing of layers running helyxHexMesh. $FOAM_APP/utilities/mesh/generation/helyxHexMesh/helyxHexMesh.C $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver

6. Clear out mesh before adding layers to try to improve memory usage. $FOAM_APP/utilities/mesh/generation/helyxHexMesh/helyxHexMesh.C $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver/snappyLayerDriver.C

7. Added keyword "dualZoneLayersScaling" to addLayerControls sub-dictionary and "cacheShellLevel" to top level helyxHexMeshDict. The optional keyword dualZoneLayersScaling (default: 1) controls extent to which layers can be moved during layer smoothing. The optional top-level keyword cacheShellLevel (default: true) allows a cached field of surface level to be calculated. This, by default, includes shell refinements levels as well. This can be expensive to perform because it requires an insideness check. $FOAM_APP/utilities/mesh/generation/helyxHexMesh/helyxHexMesh.C $FOAM_SRC/mesh/snappyHexMesh/layerManipulate $FOAM_SRC/mesh/snappyHexMesh/refinementSurfaces $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver/layerParameters

8. Fixed a bug to allow the humidityThermalSource to run with different humidity names. $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/modules/humidity.cfg $FOAM_SRC/fvOptions/sources/derived/humidityThermalSource/humidityThermalSource.C

9. Removed need to specify ddtScheme for concentrationTransport function object. Update default settings for specialised modules using this function - removed ddtScheme settings. $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/modules $FOAM_SRC/solverObjects/solvers/concentrationTransport/concentrationTransport.C

10. Changed default turbulence gradient scheme to "cellLimited Gauss linear 1". $FOAM_ETC/caseDicts/preProcessing/caseSetup/models/turbulence.cfg



11. Added logical keyword "combineFiles" (default false) which, when active, writes combined forces and moments to a single file. This provides backward compatible output for forces function object. $FOAM_SRC/functionObjects/forces/forces

12. Modified decoupledEuler implementation. Refactor decoupled Eulerian to access all relevant continuous phase data via turbulence model. Added test cases for decoupled Eulerian latealCavity and rainOnCubicBuilding, both isothermal and steady-state (simpleFoam or pimpleFoam with CoEuler). Two rain cases are momentum coupled, the others are uncoupled. $FOAM_SRC/fvOptions/sources/derived/decoupledEulerianThermalSource/massTransfer/phaseChange/Lee/Lee.C $FOAM_SRC/solverObjects/solvers/decoupledEulerianSpray $FOAM_SRC/solverObjects/solvers/decoupledEulerianSpray/phase $FOAM_TUT/multiphase/decoupledEulerianSpray/PhaseSettling/constant/decoupledEulerianProperties $FOAM_TUT/multiphase/decoupledEulerianSpray/lateralCavity $FOAM_TUT/multiphase/decoupledEulerianSpray/rainOnCubicBuilding

13. Fixed a bug where scalarTransport failed when running chtMultiRegionSimpleFoam. $FOAM_TUT/heatTransfer/chtMultiRegionFoam/windshieldCondensation

14. Added cylindrical extrusion method. Interface only differs from linearRadial by the specification of the cylinder axis. $FOAM_SRC/mesh/extrudeModel/linearRadialCylindrical $FOAM_SRC/mesh/extrudeModel/radial/radial.C

15. Fixed issue with procedural setting injection that caused references to sub-dictionaries held in fvSchemes and fvSolution to become invalid. $FOAM_SRC/OpenFOAM/db/dictionary $FOAM_SRC/OpenFOAM/matrices/solution $FOAM_SRC/finiteVolume/finiteVolume/fvSchemes

16. Major changes to interface for interpolatedInletOutlet, interpolatedFixedValue, windProfileVelocity, patchdistFunction and ABL inlet profiles. A new class "fieldProfile" was added that combines a generalised 1D distance function (patchDistFunction) with a Function1 to provide a flexible interface for specifying non-uniform inlets. This has resulted in considerable interface consolidation (for example the patchDistanceFunction is also used in the ABL boundaries). The usage of the various components is detailed in their header files. A tutorial that uses windProfileVelocity and interpolatedInletOutlet has been added (incompressible/simpleFoam/cylindricalDomainWind). $FOAM_SRC/finiteVolume/cfdTools/general/ABLProfile $FOAM_SRC/finiteVolume/cfdTools/general/patchDistanceFunction $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/interpolatedFixedValue $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/interpolatedInletOutlet



$FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/windProfileDirectionVelocity 17. Fixed issue where caseSetup would fail if the input file included function entries like

"#include". $FOAM_APP/utilities/preProcessing/caseSetup/setupDict.H $FOAM_SRC/OpenFOAM/db/IOobjects/IOdictionary

18. Replaced "Gauss skewCorrected linear" with leastSquares in the caseSetup defaults. $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/buoyantPimpleFoam.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/buoyantSimpleFoam.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/interFoamRAS.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/multiphaseEulerFoamRAS.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/rhoCentralFoamRAS.cfg $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/simpleFoam.cfg

19. Addressed issue where radiant fields would attempt to map for inter-region mapped patches where no valid radiant field exists on the other side. Added backward compatibility to thermal boundaries that use "kappa/kappaMethod", put a check in radiantField to make sure zero sized direction vectors are not employed. $FOAM_ETC/caseDicts/preProcessing/caseSetup/fields/thermal.cfg $FOAM_SRC/TurbulenceModels/compressible/turbulentFluidThermoModels/derivedFvPatchFields/temperatureCoupledBase/temperatureCoupledBase.C $FOAM_SRC/TurbulenceModels/compressible/turbulentFluidThermoModels/derivedFvPatchFields/turbulentConvectiveTemperature/turbulentConvectiveTemperatureFvPatchScalarField.C $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/radiant/radiantFvPatchScalarField.C $FOAM_SRC/regionCoupled/derivedFvPatchFields/coupledWallEnergy/coupledWallEnergyFvPatchScalarField.C $FOAM_SRC/thermophysicalModels/radiation/radiationModels/domSolar/radiantField.C

20. Fixxed issue where restarting a case used to load the value of the 1st entry in the deltaT table. Now it uses the value of deltaT for the current timestep according to the entry in the deltaT table. $FOAM_SRC/OpenFOAM/db/Time/Time.C

21. Modified fieldBlendingFactor default to add "writeControl writeTime". This should prevent the function from dumping the blending field to disk every iteration. $FOAM_ETC/caseDicts/preProcessing/caseSetup/functions/functions.cfg

22. Updated TimeDependentSemiImplicitSource to use Function1. $FOAM_SRC/fvOptions/sources/general/timeDependentSemiImplicitSource

23. Fixed sync bug in dual mesh generator when removing cells on grown up patches. $FOAM_SRC/mesh/snappyHexMesh/snappyHexMeshDriver/snappySnapDriver.C

24. Extended caseSetup to print boundary settings to screen by setting the printBoundaries to true in modificationSwitches. Also, update velocity boundaries using MRF so that initial



velocity field shows boundary velocity resulting from MRF. This is done through the following: fields::U::initialisation{fvOptionsCorrect true;}. $FOAM_APP/utilities/preProcessing/caseSetup/stateFunctions/modificationSwitches $FOAM_APP/utilities/preProcessing/caseSetup/stateFunctions/stateComponents $FOAM_SRC/finiteVolume/cfdTools/general/boundarySetup

25. Fixed bug in parallel direct mapping when processor contains multiple regions and walk fails to complete. $FOAM_SRC/sampling/meshToMesh/calcMethod/direct/directMethod.C

26. Made modifications to fieldProcess and cylindrical coordinate rotation to allow volVectorFields to be transformed into cylindrical components. $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/noSlip/noSlipFvPatchVectorField.C $FOAM_SRC/functionObjects/field/fieldProcess $FOAM_SRC/meshTools/coordinateSystems/coordinateRotation

27. Added residualControl for p in PIMPLE solvers in caseSetup. $FOAM_ETC/caseDicts/preProcessing/caseSetup/settings/fvSolution.cfg

28. Fixed a problem where AMI crashed on very bad meshes. Added a loop algorithm until the target box contains the source box and added a loop for increasing the radius of searching algorithm. $FOAM_SRC/meshTools/AMIInterpolation/AMIInterpolation/AMIMethod/AMIMethod $FOAM_SRC/meshTools/AMIInterpolation/AMIInterpolation/AMIMethod/faceAreaWeightAM

29. fixedMean and fixedMeanValue have been made 100% consistent. fixedMeanValue is now deprecated and will be removed for 3.2. The main difference was that fixedMean supported a Function1 defined mean (now both do). The keyword for the Function1 is "meanValue". $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/fixedMean $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/fixedMeanValue

30. Added time-varying input to surfaceNormalFixedValue. The new entry is of type Function1 and the keyword is "profile". Everything else is identical. The current scalar value is still stored in "refValue". $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/surfaceNormalFixedValue

31. Made changes to caseSetup config cfg files for concentrationTransport to be setup via fvOptions instead of functionObjects. $FOAM_ETC/caseDicts/preProcessing/caseSetup/solvers/modules.

32. Differentiated specialised template for assembling binary data in multiphase cases. $FOAM_APP/utilities/preProcessing/caseSetup/stateFunctions/stateComponents/multiphaseEuler

33. Replaced all instances of "inFieldOne" and "inFieldTwo" with "inField1" and "inField2" to ensure consistency. $FOAM_SRC/functionObjects/field/fieldProcess/fieldProcessFunctions.C



34. Fixed issues with turboPerformance function object. Now it outputs data to turboPerformance.dat. $FOAM_SRC/functionObjects/forces/forces $FOAM_SRC/functionObjects/forces/turboPerformance

35. Fixed issue with changing name in function object logs. File logs will now always write to the same location. Old logs will be pushed to index labelled files recursively. So, for example, at the start of execution if the functionObject wants to write drag.dat and it already exists, then the old drag.dat will be moved to drag_0.dat. If drag_0.dat exists, it will be moved to drag_1.dat and so on. The maximum index is currently set to 10 to prevent excessive file build-up. $FOAM_SRC/OpenFOAM/db/functionObjects/writeFile

36. turbulentMassFluxConcentration, relativeHumidityInletOutlet and phaseChangeHumidity were moved to TurbulenceModels\derivedFvPatchFields. This is to allow to setup these boundary conditions for both compressible and incompressible cases. $FOAM_SRC/TurbulenceModels/turbulenceModels/derivedFvPatchFields/phaseChangeHumidity $FOAM_SRC/TurbulenceModels/turbulenceModels/derivedFvPatchFields/relativeHumidityInletOutlet $FOAM_SRC/TurbulenceModels/turbulenceModels/derivedFvPatchFields/turbulentMassFluxConcentration

37. Fixed issue with purgeWrite when intermediate files are written out, for example, when debug switches are active. $FOAM_SRC/OpenFOAM/db/Time/TimeIO.C

38. Fixed boundaryMesh setup error in caseSetup where it erported an error instead of a warning when a boundary was not present in boundary file but strictPatchNameChecking was set to false. $FOAM_APP/utilities/preProcessing/caseSetup/boundaryMeshSetup.H

39. Enabled frontalArea to run on less processors than there are processor directories. This was achieved by disabling the read of decomposeParDict in frontalArea utility so that the number of processors run on takedn from Pstream::nProcs. $FOAM_APP/utilities/preProcessing/frontalArea/frontalArea.C

40. Fixed problem in setSet with writing VTK files for new sets. $FOAM_APP/utilities/mesh/manipulation/setSet/setSet.C

41. Fixed issue with searchableSurfaceQueries::findNearest when using searchableCone. $FOAM_SRC/meshTools/searchableSurfaces/searchableCone/searchableCone.C

35. Removed all Qsolar references. Qsolar is no longer supported. All radiation now uses radiation model interface. $FOAM_APP/utilities/postProcessing/miscellaneous/postComfort/postComfort.C $FOAM_SRC/TurbulenceModels/compressible/turbulentFluidThermoModels/derivedFvPatchFields/turbulentConvectiveTemperature

43. For the sample utility, fixed an issue where if you sample a cloud of points and use a parallel case, resulting sampling is repeated on some points. $FOAM_SRC/sampling/sampledSet/cloud/cloudSet.C

44. Changed diffusivity units in caseSetup configuration files to make it consistent for compressible cases. $FOAM_ETC/caseDicts/preProcessing/caseSetup/fields/diffusivity.cfg

45. Modified caseSetup to provide "materialName" entry for all material properties. Tested for single phase fluids, solids and VOF multi-phase fluids. $FOAM_applications/utilities/preProcessing/caseSetup/stateFunctions/stateComponents

46. Rename output field from P to pstatic to support Windows systems. $FOAM_APP/utilities/postProcessing/scalarField/kinematicToStaticPressure/kinematicToStaticPressure.C

47. Changed the default turbulent Prandtl number from 1 to 0.85 for compressible solvers. $FOAM_SRC/TurbulenceModels/compressible/EddyDiffusivity/EddyDiffusivity.C

48. Changed caseSetup so that it will now output dimensions for surface tension (sigma) interFoam and compressibleInterFoam setting. $FOAM_

49. Fixed issue caused when using radiation models with cases that include empty patches. Models with empty patches to run in case of radiation. $FOAM_SRC/finiteVolume/cfdTools/general/explicitScalarWaveSolve/explicitScalarWaveSolve.C

50. Fixed a compacting operation which can produce self-assignment error in snappyHexMesh. $FOAM_SRC/mesh/snappyHexMesh/meshRefinement/meshRefinementMerge.C

OpenFOAM 2.3 up to Q3 2016 version of OPENFOAM. 2. Added a new conjugate heat transfer solver helyxCHT.

$FOAM_APP/solvers/heatTransfer/helyxCHT



3. Restructured the caseSetup utility and the caseSetupDict file structure to allow for multi-region support. $FOAM_APP/utilities/preProcessing/caseSetup

4. Added an allRegionsToMesh flag to the mergeMeshes utility to allow it to combine all region meshes into a master mesh. $FOAM_APP/utilities/mesh/manipulation/mergeMeshes

5. Updated the function object input-output functionality to support the new multi-region capability.

6. Replaced the exactNamed and partialNamed methodology with regular expression support throughout. Removed all instances of exactNamed and partialNamed not actively used for backward compatibility. All components now use exact match, regular expression match or group match. The exactNamed and partialNamed convention is still supported for backward compatibility, but is deprecated.

26. Added a new boundary that uses the profile interface from the LEMOS ABL turbulent inlet and the DFSEM algorithm to produce a turbulent inlet for ABL inlets. $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/inflowGenerator $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/SBMABLInlet $FOAM_SRC/OpenFOAM/primitives/random/random11

2. Upgraded the caseSetup utility to include new Coupled solver capabilities for automatic setup of DES simulations. $FOAM_APP/utilities/preProcessing/caseSetup

3. Improved the multiphaseEulerFoam solver to p_rgh formulation in order to improve stability at sharp interfaces. Also, updated the caseSetup defaults to use p_rgh to account for the change in the multiphaseEulerFoam solver. $FOAM_APP/solvers/multiphase/multiphaseEulerFoam $FOAM_ETC/dictData/caseSetupDict.stateData.multiphaseEulerFoamLES

4. Improved the caseSetup defaults for interFoam best practices for better stability in LES cases. For example, interfaceCompression is no longer used in div(phirb, alpha), correctPhi no longer needed in static mesh cases and CrankNicolson is used as the default ddt scheme rather than backward ddt scheme for LES. $FOAM_ETC/dictData/caseSetupDict.stateData.interFoamLES

5. Added a kOmega SST DES and DDES models as outlined in: Mikhail S. Gritskevich, Andrey V. Garbaruk, Jochen Schütze, Florian R. Menter. Development of DDES and IDDES Formulations for the k-ω Shear Stress Transport Model. Flow Turbulence and Combustion, April 2012. $FOAM_SRC/turbulenceModels/incompressible/LES/kOmegaSSTDES $FOAM_SRC/turbulenceModels/incompressible/LES/kOmegaSSTDDES

6. Added a dynamicSmagorinsky LES model for incompressible flows and support in caseSetup. $FOAM_ETC/dictData/caseSetupDict.turbulenceProperties

7. Added an optional keyword in the helyxHexMesh utility which can be used to activate/deactivate a geometry during the meshing process. $FOAM_APP/utilities/mesh/generation/helyxHexMesh

Bugs Fixed / Maintenance 1. Corrected a divide-by-zero bug in effectivenessHeatExchangerSource fvOption (all versions).

$FOAM_SRC/fvOptions/sources/derived/effectivenessHeatExchangerSource 2. Fixed an incorrect integer division that was resulting in reduced AIJ turbulent energy

expression in turbulentABLInletVelocity inlet. $FOAM_MOD/LEMOS/libLEMOS-2.2.x/boundaryConditions/turbulentAtmBLInletVelocity



3. Corrected a mass imbalance issue in multiphaseEulerFoam by removing interface compression at physical boundary faces. $FOAM_APP/solvers/multiphase/multiphaseEulerFoam/multiphaseSystem

4. Corrected a divide-by-zero error in the MULES interface capturing scheme. $FOAM_SRC/finiteVolume/fvMatrices/solvers/MULES

5. Updated the 6DoF solver point constraint to now support both “point” and “centreOfRotation” keywords. If both are present, centreOfRotation takes precedence. If none are present, then it will produce an error and request that centreOfRotation be provided. Take note that future versions will only support the keyword "centreOfRotation". $FOAM_SRC/sixDoFRigidBodyMotion/sixDoFRigidBodyMotion/constraints/point

6. Minor changes have been made to update to the default values of siCoupled and tiCoupledLES fvSchemes in caseSetup. $FOAM_ETC/dictData/caseSetupDict.stateData.siCoupled

New Features 1. Added new scaleUprime utility to scale instantaneous velocity components as: U = UMean +

(U - UMean) * (1 + alpha). Requires U and UMean fields. Typical alpha values: 0 to 1. $FOAM_APP/utilities/preProcessing/scaleUprime

2. Added “materialName” tags to materialProperties database for improved compatibility with HELYX-GUI. $FOAM_ETC/dictData/caseSetupDict.materialProperties

4. New “probes” function created so that that face sampling uses the face closest to the point, instead of the point closest to the cell centre. This substitutes “volProbes”, which has been deprecated. $FOAM_SRC/sampling/probes/

5. Added parameter to incompressible LES SpalartAllmaras models to allow blending of near-wall gradient calculation methods. “Cdu 1; = corrected”, “Cdu 0; = old method”. $FOAM_SRC/turbulenceModels/incompressible/LES/SpalartAllmaras/



6. Added new schemes weightBlended which combines two weights via multiplication and normalisation; volField-Weighted - uses lookup volField to construct weights. $FOAM_SRC/finiteVolume/interpolation/surfaceInterpolation/schemes/volFieldWeighted $FOAM_SRC/finiteVolume/interpolation/surfaceInterpolation/schemes/weightBlended

7. Added additional options for density calculation to buoyantBoussinesqSimple/PimpleFoam solvers. Additional options in transportProperties: rhoType - entries Beta, BetaLinear and Thiesen. If neither Beta nor TRef are specified, then TRef is calculated as the mean temperature in the domain, every iteration. This represents a change from the previous version, where automated TRef calculation only happened during the initial iteration and could cause issues with restarts. $FOAM_APP/solvers/heatTransfer/buoyantBoussinesqPimpleFoam $FOAM_APP/solvers/heatTransfer/buoyantBoussinesqSimpleFoam

8. Added “strainRate” operation to fieldProcess. Outputs scalar rate of strain. $FOAM_SRC/postProcessing/functionObjects/field/fieldProcess/

13. Added scalarMultiply to utility foamCalc. $FOAM_SRC/postProcessing/foamCalcFunctions/basic/scalarMultiply/

14. Added phase sensitive relaxation to interFoam velocity limiter. To activate add “Clim 0.5;” to fvSolution::relaxationFactors::fields:: $FOAM_APP/solvers/multiphase/interFoam23

15. Improved interFoam air side velocity limiter to be more local to the interface. Should be more stable and less disruptive of far field velocities. Only applies to interFoam and waveFoam at present. Should not be used with cases where air side velocity is important or the driving force. $FOAM_APP/solvers/multiphase/interFoam23

16. Added support for fvSolution::SIMPLE, PIMPLE, PISO and COUPLED to incompressiblePressure utility. $FOAM_APP/utilities/postProcessing/scalarField/incompressiblePressure/

25. Prevent smoothing of internal zones faces on a grown up patch in helyxHexMesh $FOAM_SRC/mesh/autoMesh/autoHexMesh/autoHexMeshDriver/

Bugs Fixed / Maintenance 1. Corrected error in liftDrag function: porous moment had wrong sign in equations.

$FOAM_SRC/postProcessing/functionObjects/forces/liftDrag/ 2. Fixed consistency issues in compressible S-A DES class models. For example: mag strain was

used instead of mag vorticity; GIS is activated by default; other minor (cosmetic) consistency improvement between compressible and incompressible S-A class DES models were added. $FOAM_SRC/turbulenceModels/compressible/LES/SpalartAllmaras/

3. Corrected various issues in S-A DDES and IDDES incompressible turbulence models. For example: the magnitude of symmetric instead of skew velocity gradient was used in production term; corrected some stability issues; GIS Shield is activated by default. $FOAM_SRC/turbulenceModels/incompressible/LES/SpalartAllmaras/

4. Added make/clean scripts and tutorials for LEMOS module. $FOAM_MOD/LEMOS/Allclean

5. Fully integrated “bounded” scheme in best practices. Removed last vestiges of hard-coded “bounded” scheme from pisoFoam solver configuration files. $FOAM_ETC/dictData/caseSetupDict.*

9. Fixed incompressible SA-IDDES model to be consistent with compressible flow version. $FOAM_SRC/turbulenceModels/incompressible/LES/SpalartAllmarasIDDES

10. Corrected issue in velocity limiter that prevented “relax” call from functioning properly. $FOAM_SRC/fvOptions/sources/derived/velocityLimiterSource/

11. Corrected issue in porous media where interFoam would trigger search for dynamic viscosity “thermo::mu”. Will now search for kinematic viscosity “nu” if “thermo::mu” is not found. $FOAM_SRC/finiteVolume/cfdTools/general/porosityModel/DarcyForchheimer/

12. Removed all incompressible flux conservation terms. User should now specify the keyword “bounded” for all convection schemes where flux conservation is required.

13. Deactivated adjointShapeOptimisationFoam compilation $FOAM_APP/solvers/incompressible/adjointShapeOptimizationFoam

16. caseSetup now supports controlDict setup. Default controlDicts exist for most solvers. This does not include function object for which a dedicated section is now available. $FOAM_APP/utilities/preProcessing/caseSetup $FOAM_ETC/dictData

17. caseSetup now supports function object setup. Function objects are added via an additional section called functions at the bottom of the caseSetup file. All functions will warn when the minimum amount of information has not been entered. All supported functions are created from a template containing generic info such as the required libraries and commonly used settings. $FOAM_APP/utilities/preProcessing/caseSetup $FOAM_ETC/dictData

18. porousZones, MRFZones and thermalZones can now be created via caseSetup. Empty files of this kind are created by default. The list format is no longer required. Entries are simply written as top level dictionaries inside these files. This has been made possible via low-level changes to underlying array class. Example: constant{porousZones{zone1{. . . } zone2{. . . }} $FOAM_APP/utilities/preProcessing/caseSetup $FOAM_ETC/dictData



19. caseSetup state specification has been modularised to support a greater range of functionality more naturally. These modules can be combinations of several state entries or a single state. The new list include: AoA (age of air); CO2 (CO2 transport); radiation (thermal radiation on/off switch); humidity (humidity transport for incompressible flow). $FOAM_APP/utilities/preProcessing/caseSetup $FOAM_ETC/dictData

26. Utility snappyHexMesh can now refine along surface boundaries, not only surface feature edges. Usage controlled from refineSurfaceBoundary keyword in sub-dictionary castellatedMeshControls of snappyHexMeshDict. $FOAM_APP/utilities/mesh/generation/snappyHexMesh

Bugs Fixed / Maintenance 1. Added new algorithm in snappyHexMesh for zoning mesh, to perform a more robust

insideness check. $FOAM_APP/utilities/mesh/generation/snappyHexMesh

2. Function object passiveScalarTransport has been deprecated since it has duplicate functionality to concentrationTransport. $FOAM_SRC/postProcessing/functionObjects/solvers/passiveScalarTransport

3. Utility postComfort has been refactored to calculate additional comfort parameters and to provide better output. $FOAM_APP/utilities/postProcessing/miscellaneous/postComfort

5. Utility createCase now populates default caseSetupDict with functions section containing volume report for U and p $FOAM_ETC/dictData/createCase.caseSetupDict



6. All mass transfer coefficients are now post-fixed by the property that gets transported. E.g. the molecular diffusion coefficient for humidity field w is Dw (used to be just D). $FOAM_APP/solvers/heatTransfer/buoyantBoussinesqSimpleFoam $FOAM_APP/solvers/heatTransfer/buoyantBoussinesqPisoFoam

7. Each species has now its own turbulent diffusivity coefficient field. For humidity w, this is Dtw (instead of just Dt). This means that we can have independent function objects for different species without having to rely on the existence of one particular field. (In the past we could not solve CO2 without solving humidity.) Other changes: Cpv -> Cpw, Sct -> Sctw $FOAM_APP/solvers/heatTransfer/buoyantBoussinesqSimpleFoam $FOAM_APP/solvers/heatTransfer/buoyantBoussinesqPisoFoam

8. TRef should no longer has to be specified for buoyant cases that do not have Beta (expansion coefficient) specified. If there is no TRef and no Beta in transportProperties, then TRef is calculated as the initial volumetric mean temperature. This change has been incorporated in caseSetup. TRef will no longer be written by default. $FOAM_APP/solvers/heatTransfer/buoyantBoussinesqSimpleFoam $FOAM_APP/solvers/heatTransfer/buoyantBoussinesqPisoFoam

9. Added support for effect of porosity on ddt(U) term in pisoFoam. To activate needs a porosity <x>; entry in the relevant porous media section. $FOAM_APP/solvers/incompressible/pisoFoam

10. simplePorousFoam: this utility has duplicate functionality to simpleFoam and porousSimpleFoam and has been deleted

11. A minor change (Beta) has been introduced in solver interFoam to reduce parasitic currents in high surface tension scenarios $FOAM_APP/solvers/multiPhase/interFoam

12. Boundary setup tools in caseSetup now support generic boundaries (zeroGradient) $FOAM_SRC/finiteVolume/cfdTools/general/boundarySetup

13. Added “weak” boundary condition formulation to improve stability of boundary type resistiveVelocity. $FOAM_SRC/finiteVolume/fields/fvPatchFields/derived/resistiveVelocity

14. All compressible alphat and Dt wallFunctions have been consolidated to work like their incompressible counterparts. As such alphaSgsWallFunctions no longer exist and have been replaced by the unified alphatWallFunctions. Available compressible wall functions are: compressible::DtJayatillekeWallFunction and compressible::alphatJayatillekeWallFunction, compressible::DtKaderWallFunction and compressible::alphatKaderWallFunction, compressible::DtWallFunction and compressible::alphatWallFunction Tutorials have been updated to comply with new specification. $FOAM_SRC /turbulenceModels/compressible/turbulenceModel/derivedFvPatchFields

15. Added additional controls and stability measures to boundary condition type phaseChangeHumidity to improve phase change thermal coupling. New controls include steadyEvaporation and thermalCoupling. The latter will link to boundary types



turbulentHeatFluxTemp and turbulentConvectiveTemp. Uses under-relaxation of coupling heat-flux to stabilise system. This will impact accuracy somewhat in transient simulations. $FOAM_SRC/turbulenceModels/incompressible/turbulenceModel/derivedFvPatchFields/phaseChangeHumidity

16. snappySetupDict can now populate surface region data using keyword setAllPatches. $FOAM_APP/utilities/preProcessing/snappySetup/snappySetupDict

17. snappySetupDict will now deleted any entries from snappyHexMeshDict referring to geometry removed from triSurface folder. $FOAM_APP/utilities/preProcessing/snappySetup/snappySetupDict

18. Speed-up of pointEdge mesh wave when running snappyHexMesh on more than 32 processors. Re-factoring produces 3x speed-up of layer addition phase on 128 cpus. $FOAM_SRC/meshTools/PointEdgeWave

19. Utility createCase now creates log directory and have added support for compressible case controlDicts. $FOAM_APP/utilities/preProcessing/createCase

20. Minor modification to function object liftDrag to generalised moment contribution to front and rear lift so that it is alongside force direction instead of y-axis. $FOAM_SRC/turbulenceModels/turbTools

21. Capturing of baffle edges during direct feature snapping has been improved in snappyHexMesh. $FOAM_APP/utilities/mesh/generation/snappyHexMesh

22. Merging of faces now performed at start of snapping and collapsing of edges now performed at the end of snapping to improve layer quality in snappyHexMesh. Edge collapsing controlled from keyword collapseTol in section snapControls of snappyHexMeshDict. $FOAM_APP/utilities/mesh/generation/snappyHexMesh

HELYX-Core 1.6-1.3 | Release date 19/11/2010

Bugs Fixed / Maintenance 1. fvDOM radiation model modified to make ray direction definition consistent throughout

entire model. Previously, two slightly different directions were defined for each ray. The inconsistent use of these directions caused stability and accuracy issues in certain situations. $FOAM_SRC/thermophysicalModels/radiation

2. Corrected reflected fvDOM radiation scaling. Since there is a discrete number of DOM rays shining is specific directions, it is possible for a flat surface element to be aligned such that it cannot radiate in a complete hemi-sphere. This was not taken into account in the standard implementation when scaling the energy intensity for individual rays. The net effect was that energy was lost (because less energy can be emitted than the incident amount) and the entire system would eventually cool to absolute zero. This loss is very slow and much more pronounced for small numbers of rays and large surfaces oriented parallel to some of the rays. In fact for certain ray/geometry combinations no loss would occur - this is why our validation



case did not pick up the problem. It had a large number of rays, none of which were parallel to the outside walls of the standing manikin case. $FOAM_SRC/thermophysicalModels/radiation

5. Human comfort physiological boundary conditions: 4 boundary conditions and a dedicated function object for gas concentration transport. The new boundaries are based on empirical relationships for heat, humidity and CO2 production in heterogeneous groups of humans. The functionality currently only operates in conjunction with the buoyantBoussinesqSimple and PisoFoam solvers. Humidity has to be enabled for CO2 transport to work as the CO2 transport relies on the turbulent diffusion coefficient used for humidity. $FOAM/src/turbulenceModels/incompressible/turbulenceModel/derivedFvPatchFields/groupOfHumansCO2 $FOAM/src/turbulenceModels/incompressible/turbulenceModel/derivedFvPatchFields/groupOfHumansHeatFlux $FOAM/src/turbulenceModels/incompressible/turbulenceModel/derivedFvPatchFields/groupOfHumansHumidityFlux $FOAM/src/turbulenceModels/incompressible/turbulenceModel/derivedFvPatchFields/turbulentMassFluxConcentration $FOAM/src/postProcessing/functionObjects/solvers/concentrationTransport

Can be used with steady-state flow field with transient temperature and/or humidity. $FOAM/applications/solvers/heatTransfer/buoyantBoussinesqPisoFoam

8. Added directFeatureSnapping in snappyHexMesh to prevent snapping to surface boundaries which are not also region boundaries. $FOAM/applications/utilities/mesh/generation/snappyHexMesh

9. Boussinesq setup in caseSetup will now write Beta (thermal expansion coefficient) to tranportProperties if found. It also reports which dictionaries are written to file. $FOAM/applications/utilities/preProcessing/caseSetup
