MSH2 reader inside MOAB does not support $PhysicalNames section.
Issue #116
new
Currently, if the provided valid mesh file has a section with $PhysicalNames, the section is not recognized. And consequently, the mesh file is rendered incorrect.
Sorry about the delay in getting back. We currently do not store the actual physical names from the file. Only the material ID attributes are stored.
You can probably modify the Gmsh reader to accommodate this directly if needed. We would also appreciate a PR if you have a verified patch that handles the physical names in the Gmsh reader.
