Drag Coefficient too high

Hey Tina,

Your setup looks OK. I noticed that the relaxation factors, under numerics, are slightly different. You used 0.3; 0.7; 0.7; 0.01 for pressure, velocity, k and omega respectively. The step by step tutorial suggests 0.2; 0.5; 0.5; 0.5.
What Cd values were you hoping to get? I tried to find other public FSAE projects but most of them don’t have drag coefficients set in result control :expressionless:
This project by pfernandez resulted in a 1.23 Cd although his geometry is a little bit different from yours. Power User @fsite has a lot of experience with FSAE, maybe she will have further insights.
