Chuyi, i finished it. But i think in the second step > ConstraintMatrix::get_constraint_lines() should be > (*constraint_entries)[0].first by calling constraint_entries = > ConstraintMatrix::get_constraint_entries(* IndexSet::ElementIterator), > right? > Yes, you're right ConstraintMatrix::get_constraint_lines() should have been ConstraintMatrix::get_constraint_entries(). Also note that there might be more than one constraint entry and that not all the coefficients are 1. This in particular happens if you consider adaptive mesh refinement. Otherwise, I am happy to hear that this worked well for you!
