drag around a car model
 

Hello everyone.
Am simulating steady air flow around a car model and could not account for the reason why I had two alternating converging results. i.e two values of drag and lift coefficient repeating interchangeably. Can someone suggest a solution. thanks

You can try a small amount of yaw. 0.5 degrees can help smooth things out if you are after 'steady' results.

Alright, thanks.
