Moving Reference Frame (MRF) with UDF
 
Hello everybody!

I need to do a transient simulation of a rotating shape. I want to use a profile law to control rotational speed. My geometry is not axisymmetric so I cannot use properly moving wall conditions.

Does anyone know if it's possible to use a User Defined Function (UDF) with a Moving Reference Frame? I don't see any available field to hook my UDF... is there however a way to make rotational speed change during simulation?

Thank you very much!
