Hello! I have now added a method to DofMap, which tabulate a map between vertices and dofs. It will only work for DofMaps with dofs on vertices. So basically for any CG 1 FunctionSpaces and will raise error else wise.
Usage: from dolfin import * import numpy as np mesh = UnitSquareMesh(10,10) V = VectorFunctionSpace(mesh, "CG", 1) u = Function(V) u.interpolate(Constant((1,2))) vert_values = np.zeros(mesh.num_vertices()*2) vert_values[V.dofmap().tabulate_vertex_map(mesh)] = \ u.vector().array() print vert_values In parallel the map will follow the local dofs. This means that some values in vert_values above will still be 0. The 0 values will then correspond to vertex values which are owned by another process. In C++ the method returns a std::vector<std::size_t>. Questions: Does the name "tabulate_vertex_map" work? Should a version of this method exist in other classes. FunctionSpace, Function (without the mesh argument of course)?
