Hi ,
I want to build a cross-like 3D pipe connection. What I did was to unite two pipes of same diameter to form a crosslike connection. The problem with that is I am not able to mesh using hexagonal wedge or cooper mesh. I think it is because of the faces formed at the center after uniting the two cylinders. Any ideas to make such a volume having a structured mesh. It would be great if you can give some ideas. Thanks, Suresh |

As far as I know, the cooper's algorithm of Ted Blacker's is not fully 3D. Gambit is a crude meshing tool compared to the stand alone preprocessor. Contact them and ask how they meshing cross-pipe. You could even contact fluent. Everybody knows how to make it with all hex. Check the list of the company of the resources section.

Hi
You can do it, because I have seen people who has done this type of mesh before!! Please, read the paper of Sierra Espinoza F.Z, Bates C.J., O'Doherty T. Turbulent flow in a 90 pipe junction Part 1: Decay of fluctuations upstream the flow bifurcation. Computer & Fluid 29 (2000) 197-213 They explain how to mesh a simmilar domain!!

There is a 3-pipe joint case fluent tutorial mannual. That case shows how to mesh with hex. You may have a look.

Hi
The Fluent case that mention jx I don't think that you can be used it. It seems to me that you want to model a T or a + domain, not an intersection of two elbows, which is the case presented for fluent. Some people cannot realize the complexity of meshing a T pipe domain. I wish you good luck Alex Munoz |
