Basically for every different angles 0, 3,5,9 everything is just fine with the lift coefficient.

But with the drag there is a problem, drag coefficients are negative (!) and they have various differences compared to exprimental values. Why only drag have the problem?

These are my settings: Could you please check them? Thank you!
