Hi guys,

Does anybody know how Fluent calculates the lift and drag coefficients for an object that is rotating in a sliding mesh? I'm simulating a VAWT and when you create a report definition it asks for a singular vector, I put a vector that is perpendicular to the aerofoil chord line.

I've heard people say that Fluent calculates the lift for you at different rotational angles, but is that still perpendicular to the aerofoil? Or would it change in relation to inlet wind vector?
