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 -ModelType Mimetic
Kind regards,
Martin

Hi Bernd,
Thank you so much for your help.
Please let me know if you have any progress on the decouple 2p2c in
parallel.
Concerning 2p decoupled adaptive + parallel simulations, your
comments lead me to run /test_3d2p/ in /dumux/test/decoupled/2p/ in
parallel and I obtained the following error message:
######################################################
No model type specified
Default to finite volume MPFA l-method model
Dune reported error: Dune::NotImplemented
[storeBoundaryInteractionVolume:../../../dumux/decoupled/2p/diffusion/fvmpfa/lmethod/fvmpfal3dinteractionvolumecontainer.hh:2031]:
Boundary shape not implemented
######################################################
It seems that there is a problem when storing the boundary interaction
volumes in the /mpfa-lmethod///. My test domain dimension is 10x10x10
[m x m x m] with the grid 20x20x20, all boundaries have id 1. I
haven't tested yet decoupled 2p - 3d parallel + adaptive using
/mpfa-omethod/tpfa method/. Please let me know if you have any
additional suggestions.
Kind regards,
Tri Dat

Hi Tri Dat,
I just tried to run test_dec2p2c in parallel and it seems that at
least the output is wrong. While the pvd-file contains pointers to
correct parallel pvtu-file names, only sequential vtu-files are
written. I will investigate this further.
In any case, to run in parallel, you need to switch the
LinearSolver to the AMGBackend in your problem file by adding
#include <dumux/linear/amgbackend.hh>
and adding/changing something like
SET_TYPE_PROP(TestDecTwoPTwoCProblem, LinearSolver,
Dumux::AMGBackend<TypeTag>);
Decoupled 2p adaptive and parallel is possible as far as I know.
However the 2p adaptive stuff only works with ALUGrid and that
means that one has to use a 3d test case because 2d ALUGrid is not
parallel. I will try to set up a corresponding case.
I assume that decoupled 2p2c adaptive and parallel is a larger
task. Since we would also like to have it, we can put it on our
to-do list, but it is hard to estimate when we actually can do it.
Kind regards
Bernd

Dear DuMuX,
I would like to know whether there is any test case of 2p2c
decoupled model which works correctly in parallel mode?
I tried to run the parallel simulations of all examples in
/dumux_v2.6/test/decoupled/2p2c with mpirun but I obtained always
the results of sequential simulations.
Another question always on parallel simulation but concerning the
adaptive grid refinement, can we implement the adaptive grid
method with 2p/2p2c model in parallel mode?
Thank you in advance for your reply.
Kind regards,
Tri Dat
