I'm not permitted to download or open anything from the Forum. It's the compromise with Legal that allows me to answer anything on here. 

If you're running the model in 2d make sure there are no faces selected in the contour panel. In 3d create a surface on the mid plane, or anywhere else that's useful for post processing. 

Separation - as in flow detaches from the surface. I'm a Chemical Engineer, well that's my degree from well over 20 years ago, but I'm fairly sure wings work better when the flow is attached to the surface.
