huihui New Member Huihui Wang Join Date: Jul 2012 Location: Mississippi Posts: 17 Rep Power: 13	Hello, everyone! I want to simulate the flow in the channel, but I don't know how to difine the free surface upside in FLUENT boundary condition. What I need is 'free slip wall' (in CFX I can find it, but I should use fluent), but I didn't find it in the 'boundary condition box'. could anyone tell me how to deal with it? use 'stationary wall' or 'moving wall'? Thanks!
