# Is it possible to obtain the lift and drag coefficients of a 3D body in ANSYS Fluent?

Is it possible to obtain the lift and drag coefficients of a three dimensional body in ANSYS Fluent? Or, would it be acceptable to take the coefficients of several cross-sections along the wings and body and perform a weighted average calculation to find the lift and drag values for the entire craft?

• For sure you will get results but how accurate do you need to be? Fluent (and any CFD code) has severe restrictions and assumptions. Also, all CFD codes require a specialist (if not expert) in order to give reasonable / acceptable results, for non-basic problems. Sep 12 '17 at 16:55

For drag, first the $C_{D_0}$ of all components in the table underneath are determined, and then the lift of the wing, body, tailplane etc as function of angle of attack are added.
