Dear friends,
How can i solve this curvature in meshing of NACA 0012 closed TE and disappearance of vertical lines of the cells in the triangular blocks in the images airfoil1.JPG airfoil2.JPG |

Did you follow the guide in these 3 part series on YouTube: https://www.youtube.com/watch?v=tYrbScUH9RE. Highly recommend ICEM User's watch these because there are so many questions posted here about meshing for aerofoil simulations.

I have applied the steps on my case and the mesh looks well.
but, i found some errors while checking quality of the mesh and i did smoothing three times. These are all what i face now, and the mesh can't be transported to FLUENT airfoil2.jpg airfoil3.JPG airfoil4.jpg airfoil5.jpg |

The element size transition in the streamwise direction at the trailing edge is far too high. Aim for less than 20%. Likewise for the elements in the hexa block at the leading edge.

Ireduced the cells' size to improve aspect ratio and the quality, but i still facing the problem of uncovered faces and single edges around the airfoil.
