Dear community, I have a problem with the drag coefficient regarding unrealistic or negative numbers.
I am trying to find the drag coefficient for the simulation “tunev2.2” but no matter what I am trying there is always the same frustrating result which is either a number above 2 or below zero which both are not possible for this rectangular shape.
This is my first question and I apologize if I didn’t provide enough information. At the same time I would like to thank all in advance for answers. (I have already looked at the previous similar questions and answers which didn’t helped.)
