3D wing mesh

Hi, I am trying to mesh a wing in a wind tunnel test section. I had no problems with the 2D model but am not really sure how to proceed with 3D. I thought it would be as easy as sweeping the meshed faces in 2D into a 3rd dimension but that didn't work. I would appreciate any other ideas. Sandra

Sandra,
First of all, are you using Gambit? or some other meshing package? However, if you are using Gambit, try this. In order to mesh a 3D volume, which in your case is a 3D wing section inside a wind tunnel, mesh the wing faces first. Try using a very fine mesh to get good results. I would surface mesh the wing by using a triangular mesh and laying a prismatic boundary layer to resolve the boundary layer. From there you can do your volume mesh either in Gambit or Fluent T-Grid, its up to you. Let me know if you have any problems. |

See the Gambit tutorials. The last tutorial deals extensively on meshing a wing. Hope it will help you.

r u making map mesh in 2d . how u did divide ur domain to get map mesh.
i would suggest u to sweep ur 2d profile and then mesh without deleting the 2d mesh. |

Hi, thanks everyone for your response. I made some progress but still not there yet. When trying to mesh the test section, outside control volume I keep getting an error that initialization failed to mesh 451 nodes. I tried playing with different size functions but that didn't seem to help. Anyone ran into something similar and may have a clue what's going on?....I'd appreciate any input.
