Hi Johannes,
it sounds like you want to solve (Navier)Stokes on an explicitly resolved pore geometry? Or do you want to use Darcy's law without resolving the pores but using saturation, permeability, porosity and so on? The first case would currently be impossible with Dumux since we don't have a two-phase Stokes model. The second case would be feasible, we could look at how much time it needs for one time step and then estimate the overall cost.

Could you help me with getting an idea about the computational demands? More specifically: How much days would I approximately need to … .. model water and air flows (2c2p) under transient conditions in soil (without fissures or similar) .. .. and a perfectly conservative tracer transport with it (say D2O) .. .. in a 3-D domain with 250 megavoxels … .. using an Intel Xeon with 40 CPUs @2.4 GHz, 128 GB RAM? Will it be hours, days or years? Will it run at all on such a system? Thanks a lot for your help, Cheers from Sweden, /John --- När du skickar e-post till SLU så innebär detta att SLU behandlar dina personuppgifter.
