Dear,

I'm studying mesh generation for external simulation of wing-body.

The body has sharp LE, TE and wingtip, so I have no choice without
H-H block.

The problem is, Fluent said orthogonal quality is less than allowable value, 0.01 while ICEM-CFD showing good quality(determin. > 0.8, angle>0.3)

I thinks this is due to very high aspect ratio in away from body(far field region), up to 100,000.

I copied edge parameter from near body to far field for uniform cells.
But some of this community said that some effot of setting each edges parameter respectively is need to have good quality.

I attached a picture to help understanding.

Best & Regards

Can you attach a picture of the blocking, edge mesh parameters and value of Tgrid skew quality in ICEM
