Dear All,

I have been working on multiphase flow through a complex geometry having porosity 0.25. I have patched it with oil and high-salinity brine. At the inlet I am flowing low-salinity brine. It is a pressure based, laminar, species transport without chemical reaction problem.

I am opting for a VOF steady state simulation since I wanted to pressure drop at water breakthrough and volume fraction of residual oil.

Even after 3500 iterations the solution is not converging even after using a coupled solver.

Please guide.

Thanks in advance
