Rectangular Open channel Flow( Hepl needed :) )
 

Hi
I am a beginner. I am trying to simulate an open channel flow in Fluent. I have a velocity inlet and pressure outlet. Using the VOF model. upper face is a pressure inlet. I have patched the volume fraction of water to 1 in the bottom register that i have created. I want atmospheric pressure at top. Can someone help me with the inlet conditions I am stuck!!!
