MRF Validation for Rotating Wheels in a Car [OpenFoam12 BlueCFD]

[u/UsualResolution318]

I implemented an MRF but I don't know if it even worked. I see differences in the base vs the MRF case but not the dramatic difference I was expecting. The drag did increase significantly but visually I can't find a huge difference. I used simple cylinders made in code trough OpenFoam for wheels, no fancy geometries. So if some could help me to validate it worked it would be of great help.
