I am creating a hexahedral mesh on a 3D airfoil in ICEM. I checked the aspect ratio of the grid, which reported values of 1-31500, which is a very high number and shows most of the very large elements produced behind the airfoil.

 

 

Should its values be reduced? and how ?

Is it necessary to create a smaller block near the airfoil?

Regards.

Hello,

You can try to increase the number of divisions horizontally. This can also reduce the AR.
