  Hi,
  
  I'm having some mesh quality issues when generating a 3D simulation of a FS car. This is the result I get when I evaluate the quality:
  
  Minimum Orthogonal Quality = 2.05924e-04 cell 61404 on zone 3 (ID: 61405 on partition: 0) at location ( 2.98001e-01 1.21735e-01 2.38366e+00)
  
  (To improve Orthogonal quality , use "Inverse Orthogonal Quality" in Fluent Meshing,
  
  where Inverse Orthogonal Quality = 1 - Orthogonal Quality)
  
  Warning: minimum Orthogonal Quality below 0.01.
  
  Maximum Aspect Ratio = 1.60438e+03 cell 61638 on zone 3 (ID: 61639 on partition: 0) at location ( 4.34346e-02 1.48814e-01 2.38796e+00)
  
  Do you have any recommendation on the quality of the mesh I could do to improve this?
  
  Thanks,
  
  Tomos.

  Please select orhtogonal quality in meshing. then you can check where are those elements. please see following video to locate bad cells.

  once you locate the locations, you will need to do mesh or geometry modification.
  
  please do geometry modification if it has sharp angle or small faces or tangency etc.
  
  in meshing you can change the face or edge sizing to reduce mesh skewness.
  
  there are many posts regarding mesh quality on this community. please search.
