Automotive Aerodynamic Balance

How do I calculate this in star-ccm+? I am assuming it is done in reports like finding force or coefficients. I would like to basically read out what the coefficients of lift is at the front and rear axle.

Bump. I know plenty of people use Star-CCM for automotive aero analysis. Is it in the manual and I just didn't see it?

Hey Plucas

If you see the first tutorial of STARCCM+ on the ahmed reference body, it will help you to understand and hopefully clarify your doubts

I looked into it.... I believe I can calculate it from an XY Plot. I plotted pressure coefficient along the x direction (length wise down the car). Now I have been looking where I can find the center of pressure with no luck. Is this even the right direction to be going in?

Any ideas on if I am doing this correct?
