I currently run a aerodynamic analyses auf a car body and use a symmetry boundary condition to reduce calculation effort.
When I have to input the value for reference surface should I only use the halfe of the real suface area of the body for the reason I only calculate the half of the car? Or calculates the programm the resultes with consideration of the symmetry boundary condition when I do input the reference surface value for the complete projected body surface?
It would be nice to get a helping answer.
Thank you very much.
