Change the grid size at the trailing edge of airfoil

Hello,
I used blocks to have a structured C-Type mesh for an airfoil. But now I have a problem. I need Y+ to be less than 1 on the first layer of boundary layer and this makes the first layer over the airfoil very thin, but this thin layer also goes after the trailing edge where the velocities are HIGH and this causes a high CFL number there. I just want the thin boundary layer mesh to be only around the airfoil and not after the trailing edge. I want the trailing edge mesh gets coarser (The area is shown in the image below). How can I do that? Thank you in advance. |

Hello,
Another method I think you could try is making a Y-grid with a 1/4 O-grid, as in the videos: http://www.youtube.com/watch?v=tYrbS...3&feature=plcp |

Hello aero_head,
Could you please update the youtube link because the video is down. Otherwise I am not able to erase that clustering in the trailing edge following the video. In case that you know alternatives to erase that clustering, please let me know. I would be pleased to hear your proposals. Thanks in advance. |
