I suggest you visit https://aeroptimal.com/mesh (you must create an account to use this module), where you can create a full structured airfoil mesh - https://youtu.be/4Opu0zk7gFk . You can export .su2 .msh .foam .vtk

When I do it with geometric options I don't get mesh at all. And the inflation layer doesn't look good in the tail of the airfoil. And also the tetra elements sorrounding the tail of airfoil are in my opinion way to big. I post a picture that shows how does it look like. Can I make it somehow better?

Also about controling the tetra growth from the airfoil (over the inflation layer). I did it by making a rectangular shape and by splitting the FLUID surface into two parts, and then by setting parameters to the surface (max elem size). Is there any other way to make the mesh more densy around the airfoil? Because then in fluent i get parts like "fluid shadow" and I think they are messing with my results. Because although i get nice convergence my results are fully wrong.
Thanks for every answer because I'm getting confused..

Maybe one more question? How acurate can the tetra mesh + inflation layer be? Because with an structured mesh i got accuracy about 5% to air tunnel results(Cl), and this highly satisfying for me. But what about tetra?

Hi
I the same problem How did you resolve it
Thanks
