Dear Bruno, I am not expert, but OpenFoam has Snappyhex mesh feature that might help you. Check the link below. http://www.wolfdynamics.com/wiki/meshing_OF_SHM.pdf Regards, Heena On Mon, Jun 8, 2020 at 6:22 PM Bruno Blais wrote: > Dear all, > I hope you are doing

Dear all, I hope you are doing well. In my endless quest for robust mesh generation of hex meshes using GMSH, I have managed to come up with a very robust strategy to generate hex-only meshes My only issue (which is a major one) is that this implies that my decomposition from tet to hex adds
