std::vector<std::size_t> dof_to_vertex_map(const FunctionSpace& space)

Return a map between dofs indices and vertex indices

Only works for FunctionSpace with dofs exclusively on vertices. For MixedFunctionSpaces vertex index is offset with the number of dofs per vertex. In parallel the returned map only maps local (to processor) dofs.

Arguments

space (FunctionSpace)

The FunctionSpace for what the dof to vertex map should be computed for

Returns

std::vector<std::size_t>

The dof to vertex map

std::vector<dolfin::la_index> vertex_to_dof_map(const FunctionSpace& space)

Return a map between vertex indices and dofs indices

Only works for FunctionSpace with dofs exclusively on vertices. For MixedFunctionSpaces dof index is offset with the number of dofs per vertex.

Arguments

space (FunctionSpace)

The FunctionSpace for what the vertex to dof map should be computed for

Returns

std::vector<dolfin::la_index>

The vertex to dof map
