How to calculate angle of attack from CFD post for a wind turbine?

Hi, I have run Sliding mesh analysis for Wind turbine for speed of 7, 10, 15, 20 and 25 m/s.

Does anybody know how to calculate angle of attack along the blade span in CFD post?

My blade is tapered and twisted.

How did you manage doing this i wanted to do it for an aerofoil so i used the results i got from flow time into this formula alpha(t)=alpha(mean)+alpha(amplitude)*sin(2pi*f*t) .
The results dont look so good could you tell me how you would go about doing this ?
Thank you
