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.
