Default drag prediction in FLUENT

Hi, there

I am computing a 2D foil by turbulence model. How ever, when I use the 'report force' to predict the drag on the foil, the form drag FLUENT predicted is twice of the viscous drag. My Renolds number is 1E06. From fluid mechanics, the situation seems not correct. Can anybody give me some clues?

Only half of the foil is computed, and the projection area is half of the thickness.

Thanks
