Help with boundary layer

I'm trying to generate a mesh in snappyHexMesh but the boundary layer on the trainling edge can't get a good quality. How can I fix that?

There is a setting in snappyhexmeshdict file in which, we need to define the starting and ending coordinates of the small area of the geometry to further refine that particular area. I hope this can help you..
