boundary condition problem
 
I want to calculate pressure drop in a twophase flow problem, and no data on the outlet boundary is available. In FLUENT uses "outflow" boundary condition for such cases but I dont know what I shoud do in CFX for such cases.
Help me please.

Hi,

I think you can use "mass flow on inlet" and "pressure on outlet" boundary conditions. You can give "0 pa" to outlet because you only want to calculate pressure drop so it is not important to whatever you set for Outlet Pressure. It won't change the results.
