Hello, I'm working with MultiGrid on a parallel::distributet::Triangulation and want to reorder the DoFs for the individual levels. After doing e.g. a Cuthill_McKee reordering I realised that the MGTools::make_sparsity_pattern() function throws an assertion in line 602:
Assert(sparsity.n_rows() == n_dofs, ExcDimensionMismatch(sparsity.n_rows(), n_dofs)); A simple test shows that indeed the number of level DoFs gets somehow changed during the reordering. I have attached a simple test, based on a deal.II test. The problem doesn't occur If one uses a normal (not parallel) triangulation. I'm still looking for the root cause of the problem, maybe someone has an idea here?
