Hello,
I have a good understanding of CFD and have worked with ANSYS CFX for quite some time now, but to this point I only dealt with air and wind engineering problems. Now, I wanna simulate the flow of a river over an obstacle and I can not figure out how I can set my Inlet to have both: Water at the bottom of the domain with a given height and air above the water of course. Any help is highly appreciated, thanks in advance! |

Have a look at the tutorial example: free surface flow over a bump. It does exactly what you ask.

Thank you very much. I tried the tutorial for my geometry and the solver is running right now. The only problem is that I get and error that air and water is flowing into my domain at the outlet although it shouldnt in a physical sense.

Maybe someone else has the same problem: I found the solution by adjusting the horizontal and vertical component of the coordinate system. In the tutorial y is the vertical axis.
