lift and drag coefficients around a ground vehicle
Hi
I need to obtain the lift and drag coefficients of a car directly from the cfxpost. 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 CFXPost. Then calculate the coefficients from there. Glenn Horrocks 
how to get the forces
hi Pedro ,
I made the simulation on CFDpost 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.
