I want to rotate secondary phase (bubble in water tank)
 

hi everyone,

I want to rotate bubble that is located in water tank. I decided to use VOF model. firstly I wrote a kind of UDF for making bubble in water tank. but I need rotation. for this, I think I must write a kind of DEFINE ADJUST UDF for describing u,v,w velocities (for rotation). because I think define_profile UDF can not use for this purpose.
please help me, if possible. can anyone help me for writing this type of UDF or is there any suggestion for this work. my purposes are generation of bubble in water phase and rotating it.

I need any suggestion urgently!!!!!
thanks..
