Hi, i am buzzled with an error that i get when trying to transform gmsh mesh to dolfinx with gmshio.model_to_mesh. The error i get is: ---> meshD = gmshio.model_to_mesh(gmsh.model, mesh_comm, gmsh_model_rank) --> cell_id = cell_information[perm_sort[-1]]["id"] IndexError: index -1 is out of bo…

You need to tag your volume (and potential surfaces) with physical markers, as explained in: FEniCS/dolfinx/blob/main/python/dolfinx/io/gmshio.py#L178 # geometry according to the unique index perm_sort = np.argsort(indices) assert np.a…

ok, i added physical tags for the surfaces: gmsh.model.addPhysicalGroup(2, [Omega1], 1) gmsh.model.addPhysicalGroup(2, [Omega2], 2) but this produced an error: ---> 247 meshD = gmshio.model_to_mesh(gmsh.model, mesh_comm, gmsh_model_rank) ---> gmsh_cell_perm = cell_perm_array(_cpp.mesh.to_…
