Re: [DuMuX] Parallel run of 2p2c decoupled model
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.

Hi Bernd, Thank you for your help. It works for me. I think i will just take the DgfGridCreator for parallel YaspGrid runs. I have also another question about parallel run with implicit cell-centered method of 2p model. When I try to run /dumux/test/implicit/2p/test_cc2p (CubeGrid) in parallel, I obtained this error after the first time step: [obelix2:30189] *** Process received signal *** [obelix2:30189] Signal code: (128) [obelix2:30188] Failing at address: (nil) [obelix2:30189] Signal: Segmentation fault (11) Contrarily, ./test_cc2p with SimplexGrid and ./test_box2p work fine in parallel.
