Hi there
I am getting positive drag and lift force for a 2D car body, I expected the lift force to be negative ? for instance at 70 m/s I get 1690 N for both lift and drag should not the lift be negative ? what can be wrong ? Thank you |

It can be possible depending on the shape of the car. Typically you can have a high velocity-low pressure zone just above the roof of the car that result in a positive lift.
