Hi,
You should use report menu. Report > Forces Drag force direction is the same as your free stream velocity direction. Lift force is as you know, perpendicular to that direction. You can modify your unit vectors with cos and sin functions to calculate lift and drag directions. It is easy, you can find the details in an aerodynamics book. Also, you should set your reference values such as density, area and velocity properly. Regards |
