Hi Tri Dat,
probably the MPFA L method has problems with the grid you are using.
There are some grid restrictions for the implemented MPFA methods.
Could you please send us your grid file.
You could try to run the test with the Mimetic discretization instead,
by executing
test_2p3d -ModelTy
[apply:/home/latifa/Dumux_2.6.0/dune-istl-2.3.1/dune/istl/solvers.hh:679]:
h=0 in BiCGSTAB
So please, where os the problem in my definition of the boundary
conditions? An how i can arrange it?
Best regards.

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 Samuel,
maybe I am wrong but the scvf.boundaryFlag() returns the boundaryId
of AluGrid which is only properly defined if you are using a DGF grid file.
The CO2 test uses such a DGF file, which is why it works there.
Maybe having a look at the tests in test/io/gridmanager helps.
