How to apply a periodic boundary conditions
 
I want to simulate a periodic flow in a wavy wall (see this adress for more detail): http://cfd.me.umist.ac.uk/ercofold/d...77/test77.html As I am a new user of Fluent, I count on your assistance to help me to apply a periodic boundary conditions.

See example of periodic flow and heat transfer from fluent tutorial. The upper wall will be flat, bottom one wavy. The inlet and outlet zones will be converted into periodic zones after importing into fluent.Then define mass flow on the periodic faces.

you can use UDF to define you periodicity of your boundary condition. It depend how complicated the function is.
