the rotation of my moving object changed when i passed 220-230 RPM. And I dont think its an optical illusion becasue the first time I faced this problem I ran the simulation and looked at the rotation with 0.01 s time step. 

I want to know since I need to have a counterclockwise rotation, if the motion frame imported from the fluent was clockwise (although it is in positive number ) if I define a another frame that is counterclockwise , does that effect the simulation or it does not matter if the frame is from fluent or defined by me?

 

Thanks
