Hello,
Is there a way to know which dof_index is located at which vertex.
For example, I want to "map" a dof_index that I get from
affine_constrains.get_constraint_entries(line);
to a vertex index that are in the range of triangulation.begin_vertex() and
triangulation.end_vertex().
Thank

The compiler error tells you that you need pointers, not references. So this
should work:

I tried as you suggested but it seems there is a little error still. I
found the constructor in TriaActiveIterator (5/8 constructor) though.
