hi
I use ansys fluent.13 to simulate a two phase flow(water-air) .I choose VOF model .water is incompressible and air is compressible and I have two inlet by pressure inlet boundary( water:8.45 bar & air:2 bar) and one outlet by pressure outlet(1.4 bar) but I can't converge the problem
could you help me ?

Hi mhdmk,

Your simulation was just like mine, but my phases were argon and steel, I also chose VOF and k-epsilon model, but the k and epsilon were very hard to converge. Does your situation like mine? or your continuty and monument were also can not converge ?

You can decribe your model in detail, maybe we can help each other.
