Hi everybody;
I want to simulate a free surface flow (transient) in CFX. I have to set fluid elevation as Initial Condition. The model is a reservoir that has an initial volume of water. The elevation of water surface is 2 meters. I really need your help. What should I do? Thanks, Mojtaba |

Have you tried the CFX tutorials? The free surface flow over a bump tutorial looks relevant here.

You can set initial conditions with simple commands like setting the initial liquid volume fraction to:
step((2[m]-y)/1[m]) and the gas volume fraction to automatic. |
