Drag coefficient oscillating

Hi,

I'm trying to compute the drag coefficient of a 2D car but this drag coefficient keeps oscillating. The solution seems convergerd since the residuals are low (1e-4)
Does someone have any suggestions?

Are you sure that 1e-4 is enough, I dont think so.

Please try different turbulence models regarding Re number.
