Thanks for the reply.
I did it with iteration over all cells and vertexes of each cell.
Is there any effective way to do it without iteration over cells?
For example something like inverse of cell->vertex_dof_index
which gets the global index and points to the first cell which which the
corresponding index belongs to.
