Basically, now I only have one additional factor in my local_matrix (apart

complex value (0,1). When I remove it, the Dirichlet BC get applied as
expected through the MatrixTools::apply_boundary_values function. But when i
leave it in the system - boundary conditions are no longer correct after
solving the system.
Would you please give a hint, what is going on here?
I *think* what might be happening is that you are running into a bug that
someone else just a few weeks ago discovered:
https://github.com/dealii/dealii/issues/12916
The patch for it is here:
https://github.com/dealii/dealii/pull/13041
I realize that that must have been very frustrating to debug :-( Can you try
and see whether the issue you see goes away if you apply that patch and
recompile deal.II with it?
Best
Wolfgang
