Hi Tri Dat,
it is much easier than I thought. I just forgot to specify an overlap in
the dgf file. This is necessary for YaspGrid if the decoupled models are
suppossed to run properly in parallel. Doing this right seems to give me
the correct result for parallel runs.
You can try for yourself by adapting problem and input file such that
the DgfGridCreator is used, see the attached patch. Together with an
appropriate dgf file which is also attached.
Meanwhile I will fix the CubeGridCreator for YaspGrid so that it also
works in parallel.
Kind regards
Bernd

Hi Martin and Bernd,
Please find attached the grid file I have been using for 3d2p
decoupled adaptive + parallel.
I confirm you that the test_3d2p using mimetic method works fine in
parallel.
Since I would like to run my 2p2c decoupled test cases in parallel, so
I will be very happy while listening its progress. Please keep me
informed.
Thank you once again for your help.
Kind regards,
Tri Dat

Hi Tri Dat,
I had a closer look at decoupled 2p2c in parallel. Two issues have
to be solved:
1. Apparently, our CubeGridCreator doesn't create a parallel
YaspGrid. This can be fixed easily. Until then, one can use the
default DgfGridCreator for YaspGrid and parallel.
2. In the decoupled 2p2c model, information is not transported
across the process boundaries. Since decoupled 2p and 2p2c share
quite a bit of the same infrastructure and 2p is parallel, this
also should be feasible in the close future.
Concerning decoupled 2p, I also did not succeed to run MPFAL in 3d
and parallel. The FV/TPFA works fine, also in the adaptive regime.
This needs to be further investigated.
Kind regards
Bernd
