I am having very bad results in airfoils drag and lift forces for any kind of airfoil but specielly with hight attack angle and flaps deflection. Im comparing this results with obtained in wind tunnels and Im very disappointed.

I tried many turbulences models without results and meshes.

Im using CFX and fluent.

Any sugestions?

Thanks.
