Boundary conditions for one rotating and one stationary frame

Hi guys,

I am trying to calculate the power output of a wind turbine.
To calculate the torque using FLUENT, I draw two fluid domains, one rotating frame for the blade (inside the stationary frame) and one stationary frame (see attached picture).

But I am not sure how to define boundary conditions. Can you check please the attached picture and tell me if the boundary conditions are true? Which ones do I need to change?

Thank you

You do not need any boundary conditions at the interfaces.
