hi, everybody! i am new user here. may somebody teach me how can i get the drag coefficient and lift coefficient for my 2d and 3d car air flow simulation? for example with a given dimension of length=4.465m, width=1.74m and height=1.42m. thank you.

thanks red lemon, may i know how to set the reference value? my 2d car height is 1.43m, overall length is 4.488m,if i compute from velocity_inlet(one of my wind tunnel boundary), then what should i set for my area?is't the value is equal to my car height? and the length is equal to car length? how about the pressure?is't must same with the operating condition i set?
