Pitch Axis and Reference Lenght

I want to determine the drag and lift coefficient of the car at certain velocity and to do that I just need to specify all the parameters in “Results control”.Under Results control aside from the parameters related to drag and lift we can also specify the “Pitch axis and Reference length”,my question is do we still need to include the parameters for pitch if we are only concerned with drag and lift coefficient.Would it affect the drag and lift coefficient if we disregard the pitch?

Hi!

In this case, since you are not interested in the moment coefficient, you can use dummy values for pitch axis and reference length. These two input won’t interfere with the resulting lift & drag coefficients (see the formulas used for C_d and C_l here).
