Hi, I like using Gmsh and I have recently discovered the version 3.0 with the new capabilities offered by OpenCascade.
I use it but there is an issue I never managed to fix, namely how to mesh a volume with a mix of tetrahedra and hexahedra. Please, find attached, a simple example to illustrate my question. Is it possible to make coherent both meshes, ie; the tetrahedral mesh of the sphere and the hexahedral mesh of the cube? I have read in the documentation about the QuadTri Algorithm but I never managed to make it rum. Is this the way to follow or are there other commands available in Gmsh? I would be very grateful for any help and/or suggestions. Kind regards Gérard
