Hi there!

I used ANSYS mesher to create a mesh for the control volume occupied by the airfoil.

I have a problem with the inflation layer on the airfoil surface.

Initially, the inflation layers at the tip of the airfoil has high skewness. So I solved it by creating a plane and cut the 3D airfoil at the sharp edge, then further extending the inflation layers at the sharp edge to the wake region of the airfoil. Hence, the inflation layers do not high skewness at the sharp edge.

However, by cutting the airfoil into two halves and creating an inflation layer in the wake region of the tail, the inflation layer at the head of the airfoil now has high skewness.

So anyone has any advice on how to solve this high skewness at the edge? Or better solution to create inflation layers across the airfoil of good quality?

Thank you!

This is a screenshot of my mesh after I extended the inflation layers into the wake region of the airfoil. (Purpose of this extension is to reduce the skewness of the meshes at the tail)
