I need to convert an stl (list of triangles) file into a solid mesh (list of tetrahedra) suitable for finite element methods.
I would be happy with any human-readable file format.
I tryed many softwares (not all of them yet) and MeshMixer is the first one I found that can build such a mesh (Edit->Make Solid) with my huge and complicate file.
The result looks good, now I need it outside of MeshMixer.
I tested all the export but I can't see any tetrahedra in the resulting file, did I missed something?
