Thank you very much, Jean-Paul! I have totally forgot that deal.II has
a wiki in addition to doxygen documentation!
Best regards,

Thank you very much for the answer! I was unsure that the cell
iteration order is stable, that helps a lot!

Hi Alexander,
The answer that Wolfgang gave is the one that you want to follow. But I can
give some input into your one question.

Dear deal.II users,
I'd like to ask a question concerning the use of RHS function
represented by a DoF vector from another solver.
I'm trying to build RHS of one solver (A) using solution obtained with
another solver (B) , i.e. instead of Function there is a DoF vector.
Both solvers have the same
