I'm trying to do a mesh for 2D naca0012 airfoil chord length is 0.3m,but the aspect ratio is very high and also the equiangle skewness,i used c-type mesh, for y+0.2 I use (delta S) 10e-5,i spent a lot of time to try make good mesh to be working with fluent but it keep say error, what can I do??

I put together a video describing how to generate a c-grid for a NACA 0012. You can find it at https://youtu.be/eEzxxdn-47U
