Nope, you're right: Even if eWoms and Dumux emerged from the same code base, technically they're now more like cousins than brothers. I think for your use case it's possible to use both, because that was one of the initial applications for which these codes were written. In the following, I can only speak for eWoms, since I haven't done anything using Dumux for ages. <marketing> For eWoms there's not much of a problem implementing a three phase, four component problem including an energy equation -- you can even switch between the primary variable switching (PVS) and the non-linear complementarity problem (NCP) based model by changing a single line of code. (in fact the same applies if you want to enable molecular diffusion, if you want to try out different linear solvers or preconditioners, or use a velocity model different from Darcy's law like a Forchheimer approach.) In my experience, the MPI parallelization also works quite smoothly and you can even use thread parallelization based on OpenMP (thread parallelization is currently only available for linearization but not the linear solvers, though.) </marketing> If you want to give eWoms a shot, I'll be happy to help out, but my recommendation is that you use the eWoms and OPM master versions from git because the last OPM release (which was also the latest eWoms release) currently feels like it was done during the stone ages. Maybe we should release soon?! cheers Andreas -- Any program which runs right is obsolete.
