Hello!
I have a huge problem with meshing half NACA0009 profile fin. Previously I have done meshing only in 2D and now I face a problem with doing mesh in 3D. I done tetra mesh and tried to import it to Fluent, but with no result. There was an error message "Segmentation Voliation". I`m dealing with this problem for one week. If anybody could give me some hints or an advice, I would be grateful. Thanks in advance. Screens of the problem: http://pokazywarka.pl/cn51qj/ |

Yes, of course. This is only test one, so the mesh is very coarse. Here it is:

This is only project file without geometry (*.tin) and blocking (*.blk).

As I said, I`m new here and I read that you would like to see the project .

It's not so simple as in 2D. A similar example in the topic naca0012. I was just trying to mesh.

That's one of the variants of the mesh.

Thank you very much for that. Can you give me some explanation how you done that? I see some blockin, but I have only rough idea what`s going on there. Thank you in advance.
Best regards |

1. Create 3D Block and split it as shown in pictures 1 & 2.
2. Create O-grid for area around wing as shown in picture 3. 3. Create O-grid for area inside wing as shown in picture 4. 4. Merge all vertices in thin blocks except six inside wing as shown in picture 5. Last edited by Ralen; May 21, 2012 at 05:13. |

5. Associate & move vertices as shown in pictures 6 & 7
6. Remove six blocks inside wing as shown in picture 8. 7. Associate faces of the wing to the surfaces of the wing ("FIN") as shown in picture 9 8. Align vertices along the z axis. Move vertices as shown in picture 10 Last edited by Ralen; May 21, 2012 at 07:02. |

9. Set the size for the mesh. (I use the global size 20 and 2 for the curves of the wing). Move the vertices to improve a quality!

You can also create the o-grid block along the axis Y before merge vertices.

I now doing 3D mesh for two fins, which are canted and toed in. In near future I`m going to do the mesh for 3 fins. I meet problems with assigning inner vertices (FIN1.png) to surface of the fin (FIN2.png). When I`m doing premesh, the software screams so error, and the mesh don`t have shape of the geometry.
