Hi Mustapha,
in Dumux 2.10, you have to change the linear solver to the AMGBackend to
perform parallel runs. Add in the problem file:
#include <dumux/linear/amgbackend.hh>
...
SET_TYPE_PROP(LensProblem, LinearSolver, AMGBackend<TypeTag>);
We are setting the default to AMG soon so that you don't have this
inconvenience anymore.
Let us know if this solves your problem.
Kind regards
Bernd

Hello,
We are currently doing parallel computations on DuMuX version 2.10 and
we found that the results are not similar to those in the sequential
case. This has also been observed for dumux tests
(Dumux2.10/dumux-2.10.0/build-cmake/test/porousmediumflow/2p2c/implicit
and
Dumux2.10/dumux-2.10.0/build-cmake/test/porousmediumflow/2p/implicit).
Are there things to be specified during the compilation of dumux and
dune module ? Or in the otim.opts file ?
Thank you for your reply.
Best wiches
