I tried to use code from step-22 and from the sources you recommended.
The problem is that the solution is zero over the body except the boundary
where
Dirichlet conditions were set. It is just one iteration. I don't know why
they are not in use.
Briefly, my code consists of the following steps

Dear all,
While I was learning how to use the deal.ii library, one of the my major
theoretical problems was the plethora of choices in solvers+preconditioners
available, as I mentioned in another post. For instance, most of the
Tutorial steps
mention that you can use CG when the tangent matrix
