tetrahedra (triangles) to hexahedra (quadrangles)

[WangYiKang0]

Hello，

I opened an STL model file with only points and surfaces with gmsh, and discretized the tetrahedral mesh with gmsh, and then converted it to a hexahedron with tethex is wrong.

Thanks a lot. MSH.zip

Hi WangYiKang0, unfortunately I am no longer actively maintaining this code, so I can't say for sure what's wrong, but my guess would be that STL model does not follow the same format/structure as the files generated from a Gmsh geometry (.geo), and therefore the code is not able to find the necessary information (like mapping between lines, faces, etc).
