Updates in OpenFOAM

OpenFOAM : next steps

2nd OpenFOAM Belgien Users Meeting, 17th March 20162

• New solvers : New reactingTwoPhaseEulerFoam and reactingMultiphaseEulerFoam solvers for cases with 2/several fluid phases, with multiple species and in-phase reactions.

• Implemented local time stepping (LTS) as a selectable option in each solver that previously had a separate, specialised LTS version.

• Add-ons in fvOptions for solid body motion, MRF, temperature modelling as well as rotor disk.

• Modifications in blockMesh to speed up and to improve usability.

• Bug fixes and some architectural changes.

Updates in OpenFOAM: OpenFOAM+

OpenFOAM : next steps

2nd OpenFOAM Belgien Users Meeting, 17th March 2016

• Added value in all areas of OpenFOAM: meshing (Automatic gap finding and refinement, Improvedfeature lines detecion) ,

• Improvements in parallelization:• Decomposition of surface STL data for meshing.

• New redistributePar utility, to decompose, reconstruct and re-distribute parallel cases reducing memory requirements.

• New features in boundary conditions:‣ PeriodicAMI for repeating, non-conformal geometries

‣ Humidity boundary condition

• New features in physics:‣ Solar model‣ Diffusion combustion model‣ New DES models (based on kOmegaSST and

updated Spalart-Allmaras)‣ New combustion models and solvers (moving

mesh, lagrangian, etc).

• New features in numerics:‣ New velocity damping to aid solver

sobustness during start-up of the solutionprocess.

‣ New Hybrid discretisation scheme forDES/LES applications, enabling the solverto switch between different numericalschemes. (acknowledging CFD Software E+F GmbH)

• New features in post-processing:‣ Automated picture extraction

• No need to download completemodel&results files.

‣ Run-time case termination based on userstatistics.

‣ Enhanced EnSight export in transient runs‣ Enhanced options to report forces&moments, as

well as summary of fluxes through components.

• Quality assurance is done by means of consistent development process and thorough testing:‣ Unit tests, to ensure that the new

developments did not break any other functionality.

‣ Medium size tests, monitoring performance and resources required.

‣ Industrial regression tests, to support the release process.
