Native Polyhedral MeshingPolyhedral mesh requires initial tetmesh generation and then polyhedral mesh conversion in the Fluent solver. Can be complicated, time consuming and result in too many small mesh cells
Create native polyhedral mesh
Advantages:• 2-3 times less memory• 2-3 times faster
Solver AccuracyNew settings for a better convergence and robustness for typical industrial cases
EquationsConservative Coarsening (poly and highly stretched cells)Reordering of the AMG solver
Mesh QualityWarped-Face Gradient Correction
No reordering

New featuresOverset Mesh Method
Customers expect to be able to simulate complex geometries where components of the geometry are moving relative to one another.
Overset mesh problems can be set up and solved for:Steady and transient (fixed mesh), 3-D and 2-D planarPressure-based coupled solverIncompressible density methodSingle-phase or VOF multiphaseHeat transferk-epsilon and SST k- models
BETA in 17.0: Moving mesh, compressible flow, VOF with surface tension, pressure-far-field BC, Workbench support, pressure-based segregated algorithms.
Turbulence/AcousticsHybrid RANS-LES models
Shielded Detached Eddy Simulation (SDES)– New shielding function for DES models
– Much improved shielding under grid refinement – Shielding function which ‘dissolves’ under LES conditions – Improved definition of mesh length scale and calibration
– Stress Blended Eddy Simulation (SBES)– Based on SDES shielding function, switch from selected RANS model to selected LES model– Provide shielding function to clearly define/show regions of RANS and regions of LES
