Mesh Aspect ratio and Angle

star · August 2, 2013, 08:01

Hi. I generate quadrilateral grid around 2D airfoil using C grid in ICEM. I am a beginner of CFD. I found that Mesh Aspect ratio is very high in some region. Also some angles are less than 45 degree. I want to ask that this type of mesh is ok and will it work correctly with different viscous models in fluent? I am uploading here my mesh so that my question becomes clear.

According to what an Applications Engineer told me during an ANSYS onsite visit, Fluent can handle aspect ratios as high as 0.99 now with no issue.

You are confusing aspect ratio with skewness.

Fluent can handle aspect ratio up to 10000 on doubl precision solver in boundary layer
