nrv.fmod.FEM.fenics_utils.read_gmsh(mesh, comm=<MagicMock name='mock.MPI.COMM_WORLD' id='139958333671376'>, rank=0, gdim=3)[source]

Given a mesh_file or a MeshCreator returns mesh cell_tags and facet_tags (see dolfinx.io.gmshio.model_to_mesh for more details) NB: copy of dolfinx.io.gmshio.read_from_msh verbose from gmsh

Parameters:

  • mesh_file (str,) – Path and name of mesh file NB: extention is not required but must be a .msh file

  • comm (tupple (str, int)) – The MPI communicator to use for mesh creation

  • rank (tupple (str, int)) – The rank the Gmsh model is initialized on

  • gdim (int) – dimension of the mesh, by default 3

Returns:

output – (domain, cell_tag, facet_tag)

Return type:

tuple(3)
