Free Surface flow?
 
Hello,
I'd like to ask you if you could help me to understand and give me a CCl file for the expression in CFX-pre WB12 for the following free surface model, attached in this post, there are: No slip Wall, Free Surface, Inlet - 37,18m3/s, Outlet-36m3/s, Spillway - 1,18m3/s.
Well I must be something like the Tutorial:Free Surface Flow Over a Bump, but I am getting confused with the meaning of the symbol and how to math them with the present model?

DownH

DenRef

DenH
(DenWater - DenRef)
UpVFAir
step((y-UpH)/1[m])
UpVFWater
1-UpVFAir
UpPres
DenH*g*UpVFWater*(UpH-y)
DownVFAir
step((y-DownH)/1[m])
DownVFWater
1-DownVFAir
DownPres
DenH*g*DownVFWater*(DownH-y)


Thank you for the cooperation!
Best regards to all!
