High aspect ratio mesh
 
I'm doing calculation about laminar-turbulence transition over the airfoil. And the model need y+=1, thus, the aspect ratio of mesh is very high, about 10,000, and OpenFOAM can't get convergence. Does that mean I have to draw more nodes along the cord? That will use a lot of computation resources.
Can somebody give me some advises?
