Hi Foamers,

I am stuck with a problem using interFoam solver. I am trying to simulate the immiscible displacement of oil by water (two liquids to be more general), which could be drainage or imbibition depending on the wettability.

After running the solvers in a 2D domain, which is a single channel, and proper boundary conditions, I don't have the expected results. But my problem is the accurate description of the three-phase line contact angle. If I change the wettability, other than 90, it gives me unphysical results. It seems there is a competing phenomenon between the no-slip wall condition and the constant contact angle used.

I am wondering f you guys know how to handle such condition or if is possible to modify the scripts.
