Hi there
i am doing a project on 3D Wind turbine simulation, i chose gambit to build the model and Fluent to calculate. however, there seems to be lots of problems when i try to mesh the model in gambit. Can anyone give me some suggestions? Regards, |

here is the model i built in gambit. As i marked out, the inner part is going to be the rotating part, which need to be meshed very fine. Could you provide me any good ideas on multiblock meshing on this domain. Cause i tried several ways of it, it always shows me some strange errors. Besides, i am going to use the Sliding mesh model which wouldn't be a problem, i tested a similar model prior to this.

From your geometry I guess that it will be difficult to do structured mesh for your case. Anyway you can easily do unstructured mesh in Gambit. Use size function option in it, allow mesh to grow from blade surfaces.
Another good option is use of ICEM CFD, an excellent meshing software. all the best ![]() Sabin Mathew |

Thanks for the reply, i am just looking for good method which firstly can mesh the whole domain successfully, and secondly get a fine mesh close to the blade, it doesn't have to be absolute hexa meah. i think Multiblcok meshing would be good strategy to control your mesh. And i tried several ways of dividing the whole domain into several blocks which doesn't give me results i wanted. so i am wondering whether you have good concept for multiblock mesh on my sepcific geometry.
Best Regards, |

my adviser suggested me also to use ICEM, i will come back to you later after i tried it. thanks for your reply. best regards,
