Obtaining an absurd value for the lift coefficient
I am trying to simulate a car model at some freestream velocity. Im using the realizable KE turb model for this. The problem comes when I'm calculating the lift coefficient. Although Im getting a correct value for Cd, Im getting an absurd value for Cl (arnd -77.56). If anyone has an experience on simulating flow over a car, kindly advise me on what changes should i make in order to get a correct Cl .
Thanks a lot.
