Hi all,
I-m a beginner and I have some problems.
My real aquifer is unconfined but I'm working with feflow with the confined option (because is easyer for me and the numerical effort for my pc is lower), saturated condition, and steady state flow.
I have a question for you. After I run feflow, the obtained hydraulic heads distribution, in some areas of my domain, are higher than the ground surface.
It is not possible in the real hydrogeologic setting because my aquifer is unconfined and the water table has to be below the ground surface.
How I can constrain my final numerical solution (hydraulic head distribution) to be below the ground surface?

thank you very much
