So the VisIt people said they forgot to include the xdmf plugin in v2.11
and we have to wait for the next release to get it back. Meanwhile an
alternative is suggested, see

Is there any module in deal.ii that enables this...?
Yes, you just need to create a vector with as many entries as there are cell

That looks good! Thanks for the help.

trouble implementing the estimator (previously, I just used meshworker and
it did most of the work for me but you cannot use such an approach for

Dear Wolfgang,
I wrote the sequential code first and It converged to the exact solution
using SolverCG and SSOR preconditioner.
However, the parallel code diverges at the first call to SolverCG but using
GMRES or Bicgstab it works though up to 15 DoFs not more.
First and the most

Like Bruno mentioned, if the standard preconditioners don't work, then you
will need to think about more complicated ones. Take a look at my video
lectures on preconditioners,

Output the errors per cell and visualize. Is there a pattern? Is the error
localized on the boundary, for example?
