Mesh failed

what does this error message mean? i have been using the same mesh settings on very similar models and this is the first time i got this error.
here is a link to the geometry.

Hello revolateracing,

for which run did you create the Mesh 17?

Because I cannot find it within your project.

Best regards Sebastian

Thank you for replying, the mesh is under Incompressible 4.

Hello revolateracing,

please have a look at this refinement region, you defined a region with a refinement size of 0.05m which seems pretty rough to me.

please have a look at this forum thread on the meshing of an F1 in Schools type car.

Best regards
