Hi, I encountered a problem with my code. When I do : Vp = FunctionSpace(mesh, “Lagrange”, deg) vtd_p = dof_to_vertex_map(Vp) It gives me these errors : *** Error: Unable to tabulate dof to vertex map. *** Reason: Can only tabulate dofs on vertices. *** Where: This error was encountered insid…

The problem is likely that deg is greater than 1. In that case, there exist DoFs that are not located on mesh vertices, so it is not possible to map all DoFs to corresponding vertices. See the following example: from dolfin import * mesh = UnitIntervalMesh(10) for deg in [1,2]: print("------…

dof_to_vertex_map() Is just a utility function for simple P1 function spaces. Consider accessing the information you need directly from the DofMap from dolfin import * mesh = UnitSquareMesh(1, 1) for p in range(1, 4): V = FunctionSpace(mesh, "CG", p) dm = V.dofmap() info("Polynomial order: %…
