lift and drag coefficients around a ground vehicle
 

Hi

I need to obtain the lift and drag coefficients of a car directly from the cfx-post. I know how to measure the forces in the three directions x y z with the function calculator(lift, drag and side force), but not on how to obtain the coefficients.

I searched through the archives and found limited info; I mean I learned how to obtain the forces only.

What´s the procedure for the coefficients?

Thanks!

Hi,

You need density, a reference area and a velocity. You can also get these from CFX-Post. Then calculate the coefficients from there.

how to get the forces
 

hi Pedro ,
I made the simulation on CFD-post but i do not know how to get the forces so can you tell me .

Use the function calculator and the force_x/y/z functions.
