Hello,
I have a 3D volumetric mesh inside paraview, I would like to create the ‘physical groups’ of define the ‘boundaries groups’ to use it in a simulation. currently the mesh is only composed of hexahedrals. the physical groups are on the faces, so firts i tried:
- extract surface
- group data with the extract surface and the 3D mesh
this gave (at least in logic) what i was looking for, ie., a object that has quads and hexas, but now i can not export anymore in gmsh format. I can only use it on the fully hexa mesh, but if i do this i dont have any physical group.
I would like to be able to divide my exterior faces manually in paraview (creating physical groups), regroup each of this groups with the 3D mesh and export it to a gmsh file (or a openFoam compatible format). is there a correct way to do this?
one can began from waveleght + unstructured cell types filter as 3D mesh to simulate the original workflow without the data.
