Hi Samuel, as an addition to Bernd's answer, you might have to set DUNE_GRID_EXPERIMENTAL_GRID_EXTENSIONS:BOOL=TRUE for compiling dune-grid and the grid modules. I'm not sure if this is still required. Best wishes Timo On 08.04.19 17:37, Flemisch, Bernd wrote: Hi Samuel, I think

Hi Edscott, Martin Beck implemented exactly that in his PhD thesis in Dumux 2.12 and the code should be somewhere (check dumux-pub) or ask Martin. Also this should be much easier to do in Dumux 3.0, as the structure was developed with something like sequential coupling in mind. Timo >

Hi Edscott, just as an addition: modifying the porosity-model (storage term) is a lot easier in Dumux 3.0. You simply have to change the porosity law in the spatialparams. Cheers Timo On 11.03.19 11:09, Martin Beck wrote: Hi Edscott, yes, the model assumes alpha = 1. If you want to adapt
