Meshing problem

Hi,

I’m following the Tutorial on Incompressible Flow around a Formula Student Car.

Project link: SimScale Login

As I’m creating a mesh, I am getting insane values for non-orthogonality. I have tried simplifying the CAD, however I am still getting the same problem. My question is, since the number of cells with this problem is only 759, and the number of volumes (which I assume to be equal to the number of cells) is in the 15Ms, the actual percentage of bad cells is negligible. Should I work on fixing the mesh, or can I go ahead with the simulation? If I do need to fix it, how should I do it? I can’t keep adjusting the CAD any further, I’ve done a bit already. Is there any other way? Thanks!
