Hello guys, I am trying to study the flow around NACA0012 airfoil at zero angle of attack. However, when I try to refine the octree parameter around the airfoil and generate the mesh, every single time I get different values for Lift force! Any reasons??

Is the attached data the result of an angle of attack of about 18 degrees?

When the angle of attack is taken into account in the inflow velocity component, the force in the X direction on the wing parallel to the X axis becomes negative as the angle of attack increases.
