Default problem with VOF.

I want to modelize a free surface with a vof model. My problem is similar to the tutorial about the spinning bowl and I have adapted it to my problem. The calcul works when only the oil is in the tank (the velocity field is correct) but diverges as soon as there is water above the oil. I don't know which parameters I need to modify, their influence (and above all, how to do that): -the mesh (may be near the interface) -the under relaxations factors -the pressure (there is a pressure inlet above the air) -the iteration parameters (time step, number) -the residual monitors -the multigrid controls -...

If anybody could help me... I thank you in advance. Marc

I am sorry: I don't use water but air above the oil.
