Hello guys,

I am very new to Ansys CFX and facing some problems while I am trying to simulate a wind turbine.

As you can see, I use the frozen rotor approach with a small rotating domain with the rotor and a big stationary domain. Considering the boundary conditions, everything is fine but one thing. It looks like not only the rotor itself, but also the fluid in the little domain is rotating, which is not what I want. I created the small domain by subtracting the rotor from the domain body.

My bc are:

inlet velocity
outlet avg static pressure
rotaional periodicity
interfaces: general connection, frozen rotor, pitch change none


Can somebody help me?
