2D open channel simulation
 

Hi everybody

I´m a beginner in CFD, I´m learning to use the fluent an gambit software, at this time i`m triying to simulate a open channel flow but i`m having problems with the two phases flow. First of all dont know if i must to crate a grid where the phases (water an air) are represented for diferents faces, if yes how do i do it, if not how do i have to configure fluent to have the two phases apart not mixed.

Thnaks for your help
