Hello Every one,
I am doing simulation of an airfoil for both coupled flow and segregated flow separately. But I am having problem with Lift and Drag force calculation. It shows negative values. Would you please suggest me why this is happening. I have used Mach no: 0.2, angle of attack = 0 degree, k-e turbulence model. Your cooperation is highly appreciated. Thanks, Rakibul |

9/10 problems with aero cases like this are mesh related, check your mesh.
