duci Guest Posts: n/a	HI,Every one.I have a question, As I simulate a river(open channel flow) with Fluent,I don't know how to specify the Boundary condition of the top face(the free-surface of the river exposed to the air). I think the the surface is not wall and symmetry face.Must be use Multiphase Flows model here?Now I use it just with single turbulent flow model.
