I am trying to simulate Ocean waves in Fluent for my masters project and am having some problems. Does anyone have any tips on what the best type of UDF to set up is. Does a moving wall or velocity profiles create better waves.

Hallo Claire. don't know if it is what you mean. But i would give as UDF a sinuoidal surface y()=yo+Asinwt to initialize. then you may have some waves!

Yes, you can simulate waves by using a varying velocity profile or a moving wall. I have tried both of them.

Let me know if there are better ways.

Its very difficult to simulate irregular waves.

well claire,

try to simulate the waves by deflecting the inlet wall using the sinusoidal wave form i.e. A=A0 +Asinwt It will work and i have great sucess with wave modelling in fluent.
