FSAE MRF wheel simulation

[nburjak]

Hello!
I am trying to create an mrf zone around a wheel of an FSAE car.
The results that I am getting do not seem to make sense. There is a high pressure point forming behind the wheel and a low pressure zone above it. Do I have to fix the CAD or is there something wrong with the simulation setup?
Thank you very much for your answer.

Hi there, thank you for using the forum!

I noticed that the center of rotation is misplaced:

Maybe you need to switch the y value to negative instead:

Thank you for your fast response!
The results seem to stay the same. To me it looks like the wheel is rotating in baskwards, but considering the right hand rule it should rotate forwards.

Aren’t you expecting high pressure at the front, and low pressure behind the wheel?

I agree. But maybe a view from below might further explain my question.
