Mesh Error

I am trying to simulate the aerodynamics of an F1 in Schools car. I have previously fixed other issues with meshing thanks to the forum but I have a completely new issue I haven’t seen yet.

It now says: The meshing failed on the following entities:
Flow region. The exact position is printed at the end of the Meshing Log.

This is the project link:

What should I do to fix this

This is indeed a tricky one. I would recommend you to make a probe point of the exact location mentioned in the meshing log. If the location is somewhere near the tyres, I recommend checking those connections.
Since I see you have turned on Physics based meshing, you can try increasing the Small feature suppression and reducing the fineness as well.
Overall, I would suggest trying out different settings for the mesh, especially the advanced settings, and see which one works out best for you.

I hope you are able to resolve this issue! :smiley:
