However, as can be seen in the provided images, I am having issues with the trailing and leading edges. The elemtns seem to protruding beyond the wall of the airfoil, creating a bad mesh quality and teh LE and TE. I have been trying to fix this by chnaging element sizes, using bias types, and changing various setting but none of it seems to be workign for me. Is anyone able to give me any advice on what to do in this situation?
