Open Channel Flow
 

Hi,

I have gone through the forum archive but haven't found the answers for successful simulation of open channel flow. I hope some one has answers to my set of questions.
a) In Open Channel Flow, if I use pressure inlet, do I have to make two different inlets if the case being simulated is layer of air on top of water?
b) When I try to patch the VOF value of secondary phase as 1 using registers for the area occupied by the water and then export the volume-fraction of secondary phase, I only see the value 1 on the inlet side and not in the whole domain??
c) For the Open Channel Flow simulation, the density in the whole domain should vary between 1.225 kg/m3(air) to 998.2(kg/m3) right?

Any help will be greatly appreciated.

Thanks,
Sumit
