Dear all !

I am trying to simulate a simple case of salt water instrusion. The
model is configured in steady state for both flow and transport. I
have also set a global density ratio different from zero for the
entire 3D domain of my model. The problem is I can obtain a
convergence. Setting a zero density ratio for the domain everything
seems to be ok and the program reaches the convergence in few steps.
I tried to change the grid and the number of elements, I have also
tried to increase the number of iterations but it seems that everythig
depends on the density ratio.

Do you have idea regarding my problem? did you encounter my same
problem dealing with salt water intrusion?

Thank you in advance for your help

Kind Regards
