Hi, I've been trying to simulate two phases(water and air) flow in a channel using CFX, and now I am wondering the best way to estimate water level. Is is ok if I generate an isosurface with arbitrary volume fraction of water? could you give me any advice?

Thank you for your interest.

An isosurface at volume fraction=0.5 is the usual place to put the interface.
