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

Re: 3D wing mesh
 
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.

Re: 3D wing 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.
