Help creating a DEFINE_CG_MOTION UDF

Maralady · July 29, 2013, 14:58

Hello, I want to create 2 udf (Maybe 1 not too sure) to rotate 2 cell zones inside the same geometry, I would like to know if someone can help me to clear some doubts:

DEFINE_CG_MOTION(rotation,dt,vel,omega,time,dtime)

"vel" will be 0 because it will rotate only

My main doubt is to know, how can I specify the direction of omega? I have been trying to find similar cases but have not found anything yet, please can someone help me a little bit?

For those who wonder the same:

Omega[0] = X component
Omega[1] = Y component
Omega[2] = Z component

Same for Linear Velocities
