open channel modeling
 

Hi
I'm beginner in this software(ansys-cfx).i trying to model a compound channel and i having some problem in Boundary conditions.how i can model open channels? and how i can simulation two-phase stream?
in my model, averaged velocity is 0.349 m/s and max velocity is 0.389 m/s.
please help me.
Thanks

Have a look at the free surface flow over a bump tutorial to see how to set up free surface models.

Thanks
but where is this tutorial?
anybody else can't help me?

It is tutorial number 9.

Isn't my assistance good enough for you?

Thanks dear ghorrocks i found it.
No, your help was very useful.
but for my modeling should i use those expression exactly (for open channel flows)?
I've a problem,in my modeling at the inlet boundary, height of water equal 0.08 m and also at the outlet boundary height of water is 0.08 m .
should i change these expression in this tutorial (tutorial number 9.)?
Thanks again

The tutorials give you an introduction to the field. You should be able to get your case working from there. If the tutorials are not sufficient for you then consider doing some CFX ANSYS training - have a look at the ANSYS website for training details.
