How does FLUENT calculate lift and drag?
 
Hi, I was wondering how FLUENT calculates lift and drag coefficients when you generate a force report. Specifically what equations it uses. I am assuming it uses

Cd = DRAG/(.5*density*area*velocity^2)

for drag and the similar lift equation. I don't know of any other lift or drag formulas but I thought I would ask around anyway just to make sure I am not getting answers from FLUENT that are way off but appear correct to me.
