steady-state solver for 2+ non-newtonian liquids
 

Hello,
i usually work with simpleFoam calculating pressure-drops in dies for one non-newtonian liquid. Now i want to solve the pressure drop with 2 (or more) non-newtonian liquids. The liquids are immiscable. I thought i get started with interFoam, but: interFoam is transient, my problem always is steady-state and 2D. And isn't interFoam for surface tension driven flows? I have pressure-driven flows. So, i don't know how to get started.
