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?
