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.
