Dear Mohammad,
the assumptions for coupling porous medium and free flow in dumux are based on the assumption of chemical equilibrium (as well as thermal and mechanical). A good reference for that is: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2011WR010685. You might be able to use the concept for chemical non-equilibrium as well under certain assumptions but you should be aware that this is not tested in dumux. In your example you did not include your costum newtonsolver but I am assuming that there you included the update of the velocity calculation you need for the non-equilibrium models? Right now the example you sent does not work on my machine because that is missing. This then also leads to a segmentation fault.

I attach my file for better realization best regards, Mohammad -- This email was Anti Virus checked by Security Gateway.
