How to Select Center of Rotation of Car

Hi, we are try to simulate CFD for our FSAE car. To get forces and coefficients, Simscale want us to enter center of rotation point. In following link it says that the center of rotation should be placed on halfway between the center of the front and rear wheel, on the symmetry plane and on the ground level.

Is this center of location also valid for FSAE cars? If you can help us, we will be grateful.

Hi there, have a look here under the Results Control section: Aerodynamic Flow Behavior Around a Vehicle Tutorial | SimScale

We are struggling with the reason behind choosing those very coordinates that were provided in the tutorial. How and why do we calculate them as it was told in the tutorial? E.g., why do we choose x coordinate halfway between the wheels? Should it be the case for all 4-wheel vehicle models or does it differ in any way? It is crucial for me to understand that. Thank you.
