Hi all,

I have a bit of a problem making a UDF for a rotating wall in Fluent. I want to put a velocity profile on this wall but am even struggling to make a constant speed profile work.

Does anyone know the code for a UDF that can be set in the components section of the moving wall boundary that will move this cylinder circularly at 300 rad/s?

(I know you can set this but the next step is just if statements so should be fine once i get over this hurdle)

As I am at university I cannot compile code so that rules out any CG_motion UDFs unfortunately.

Thanks,

Greg
