Dear Zhiliang, I've been doing such simulations using the VOF module in CFD-ACE. I don't see why the VOF module in ANSYS would not also work, but if you're sure it won't you can give CFDRC a look.

I know it's possible to simulate the free surface between a gas and a liquid in ANSYS 6.1 by using Volume of Fluid Method, but I don't know how to deal with the interface if both of two fluids are liquid. Any help is appreciated! Thanks. Sincerely, Zhiliang
