I am working on Diffusers on our FSAE car. My simulation has run successfully but there is one problem. The pressure plotting in the post-processing is not good. I am getting constant pressure in the whole area. Including under my car, in front of the car, and behind the car which is of course completely wrong. Also, one of the wheels is also not rotating although I have given my wheels a rotating wall function.
I am attaching the link to my project:
Can any CFD expert help me regarding this issue? Thanks in advance!!
