UDF for compressor rotor
 

Hello everyone,

I am doing a project which needs flow visualization through rotating blades. I want to simulate a single stage of a compressor containing a row of rotor blades and a row of stator blades as seen in aircraft engine but with just 1 pair of stator and rotor. I am stuck with writing a UDF to rotate the rotor only (dynamic mesh). Can anyone please help me in getting this code done.
Thanks in advance.:)
