Meshing an airfoil in 2d problem
 

Hy,

I have tried to do a C-mesh of an 2d airfoil but i have problems, the lower left isde doesnt mesh nicely, i don't know why...

Does anyone have any idea what to, i have attached a picture to show the problem.

It seems that number of grids for down part of the airfoil is not equal to that of the relative circle, so this part could not be mapped. check it~
