Hi. I am simulating an airfoil which is equipped with vortex generators.

vortex generators are the triangular bodies which are installed on upper surface of the airfoil in order to improve L/D ratio. I have just uploaded the picture of the geometry in attachments.

I intended to use Inflation mesh with First Layer Thickness option in order to control yplus values over the foil, but the Orthogonal Quality had become lower - specially in vortex generators' locations and trailing edge - when I used inflation.

what is your suggestion to use inflation without have decreases in Orthogonal Quality?

By the way, I had changed Maximum Angle to 180 in inflation advanced options, but the problem still remained. If you want another information -including mesh file or anything else- I can give you in next posts.

Thank you in advance.

You can provide fillet on the edges of the vortex generators and then use the curvature proximity feature in Ansys Fluent or a similar feature on whichever tool you are using. That helps refine the mesh around the vortex generators.
Hope this helps.
