 January 10, 2008, 18:09 lift and drag coefficients around a ground vehicle #1 Pedro Guest   Posts: n/a Sponsored Links 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!
