Thanks. I had one more question regarding... > Subdomain identifiers can be stored in different ways, as a separate > MeshFunction, or in the MeshData structure.
If subdomain identifiers are stored in MeshData structure (as opposed to having a MeshFunction "material indicators"), will they be transformed when the mesh is refined? I looked at LocalMeshRefinement::transformMeshData(), but couldnt figure this thing out. For storing the subdomain identifiers, should the array be named "material indicators", in which case dolfin will automatically make a mesh function out of it?
