Hi Dear friends
I am working with fluent (v. 12) and I want to model an 2d open channel with a wheel in open channel that raotates and moves the water in channel.
I have problems with boundary conditions.for setting BC in water and air.
should I set separate BC for water and air region?how?
regards
Sara
