(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 = 1.75935e+02 cell 720718 on zone 3 (ID: 733370 on partition: 0) at location (-6.39347e-02 1.24552e+01 2.99726e+00)
