Firstly, so sorry about my english is not fluent

I have try to learn Fluent by myself so I got so many problem which i can't solve
What i want try to do right now is simulation a Vertical wind turbine in 2D.
I have simulated a problem by 3 steps
firtly, I simulated steady flow thought the turbine. Export the force on the wing of turbine.
Secondary, apply this force to turbine by using mechanical. By this i can have rotation velocity of turbine (not true but that the only way i can do)
Thirdly, Write a UDF for rotation and complite it to my turbine. Using dynamic mesh I can simulation turbine on the working state
However, by this way i can't have rotation velocity exactly during the time.
I try to study 6dof to update the force to my turbine But i got problem is i can fix the center of my turbine stay on this place . It moving like a free object.
So anyone have idea or UDF can solve this problem please help me>

Thank you so much
