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

Denis, thanks a lot for the answer!
I think that on the first step I can use usual "interpolate_boundary_values
+ apply_boundary_values" functions,
that transform the global matrix: columns of the constrained nodes become
zero columns with diagonal non-zero entries.
In a time loop I have to

Hi Iliya,
there are numerous things that are wrong

Denis, thanks a lot for your answer and links that you provided.
However, my solution becomes in a way that the displacement values on that
boundary abnormally grow
even without assigning new boundary condition in a time loop. I attach
figures on the zero step (correct) and on the first step
Hi Ilya,
I am not away of principally simple solution, the RHS simply contains your
bilinear form times interpolated values at constrained DoFs.
What you can do is to loop over a subset of cells (those which are at the
boundary), still assemble the local matrix and do
