Lift at zero angle of attack
 

I have tried to calculate lift for wing at angle of attack = 0 degree. But i found that lift from wing not zero. Is it true? If result in CFX not zero, how to explain that?

Hi,

If it is a non-symmetric wing then it will have lift at zero angle of attack. Also the asymmetry can come from things like wall proximity the inlet or outlet. It can also come from non-physical things like insufficient convergence or mesh quality.
