Dear developers ans users, I have few more questions about dumux and viscous finger phenomenon simulation capability.
The crucial point for me is the effect of capillarity which indeed changes completely the matematical nature of the system of equations. Indeed, I should use Buckley-Leverett equations model. Also, as I experimented, for some particular combinations of permeability and capillarity the problem could become difficult to solve. That's my concern. How deeply has been investigated the viscous finger phenomenon in dumux? Shall I encounter numerical issues including capillarity? Also one last question. What is the difference/relation with opm? Kind regards, Lorenzo Campoli
