Hi Bill, Yes, I have gone through the example files. There is no problem making a grid. However, I have issues in fixing the aspect ratio at the trailing edge.

There are, however, some example grids for 2D airfoils. Have you tried just extruding those? ...Bill On 08/28/2013 04:54 AM, Adnan Qamar wrote: Hi Bill, I am trying to generate a 3D mesh over an airfoil surface. I am using hyperbolic grid generation with smothning operation to generate the mesh. I want to control aspect ratio at the trailing edge of the airfoil. Can you please suggest me how to control the aspect ration at the trailing edge of the airfoil (contract line spacing along the cut line on either side) . Attached is the cmd file I am using.
