Hi Bernd,
I reply instead of my colleague Mustapha.
1- Yes it is the result of a sequential run.
2- Yes it is the result of the unmodified co2 test
(test/porousmedia/co2/implicit/test_ccco2.cc). We have only increased
the duration of the simulation (Tend=1e6 to 1e7s) to have a better sight
Hi Mustapha,
if I try running the pamgtest
(dune-istl//dune/istl/paamg/test/pamgtest) with valgrind I get
very similar memory leaks. I can't confirm, though, that they are
different depending on the smoother (ILU0, SSOR)
of the AMG preconditioner. The test is a good starting point for a
Hi Martin,
Thank you for your reply,
Yes, I did this but I have always the same problem.

Hi Mustapha,
did you try to also change the CoarsenCriterion? You could try to
replace "Dune::Amg::SymmetricCriterion" with
"Dune::Amg::UnSymmetricCriterion". There might be some reason why a
symmetric preconditioner SSOR
is used for for the case of a symmetric CoarsenCriterion.

Hi Christoph,
Thank you for your reply. Here are some precisions
* Do see this problem only in parallel or also in sequential code? Only
with AMG or also with GMRES and ILU?
We have this problem in both case (sequential and parrallel code)
*only*when we compile with *MPI* and only with
