Dear mates,
I want to generate hexa mesh around a 3-D simple wing by ICEM. I have constructed the blocks correctly (I think!) but grid is not generated. I need your help to figure out what the problem is. Simon & Far, I think you can resolve the problem. I have attached my project files and an image. Thanks |

Hi,
There are few problems which should be rectified: 1. No of nodes are very few. 2. Delete block(s) inside wing or change its material 3. Create o-grid inside the wing tip which extends into far field. |

thanks for replying, I could get your point concerning deleting block inside the wing. But two other points are not clear to me. I have already constructed an O-grid from tip toward the far-field (as your tutorial in youtube). Please tell me why I should increase No. of points on the wing? (and how?) |

download video. Upload will take some time (may be 2-3 hrs). mean while you will get message error 403 or 404

I think the problem is with the inner face of O-block inside the wing tip. mesh is not generated for that region at the wing root and outer far-field block face.
But the wing tip is totally mesh-less (even the O-grid around the inner face). Why is that so?! Have any Idea?? |

Dear Far,
thanks to your comments I could generate the grid properly, now my problem is with boundary conditions. I know how to define BC in 2-D. But in a 3D case I have no experiences. I have tried to build 6 parts by 6 corresponding surfaces of the domain (a cube). Then I have associated the block faces to these 6 surfaces. I think this is a right method but is very time consuming. Is there any better and shorter way to define BC in a 3D geometry?! Thanks |
