Hello,
i want to convert my mesh from tetrahedral to polyhedral for the chtMultiRegionFoam. The mesh was built from ANSYS. I try the polyDualMesh. Code:
polyDualMesh 180 -concaveMultiCells combinePatchFaces 180 the number of elements are 4 times larger than previously, and there are 99% of hexahedra and only 1% of polyhedral. Before: After: I really appreciate if you help me at this. Best, Wang Last edited by wang2012; November 26, 2014 at 03:12. |

Hi bro,
There are just some extra lines brought up by paraview. U can show the perfect ploy mesh by just showing the patch, not the internalMesh. |

Hy,
there is an option in paraFoam to show the polyedral mesh correctly. It's caled "Use VTKPolyhedron". It's above the mesh parts.
