Free surface modeling
 
Hi all
I am trying to simulate free surface flow of water in CFX. I use Openning Boundary condition at outlet, but i need to define the pressure on outlet.
How can i define this pressure?

When you give the opening type boundary condition, the software asks about the direction and value. If you are giving Reference pressure as atmospheric, then use 0 as outlet pressure. Else if the reference is 0, take 1 as opening pressure.
