Hello everyone. I'm trying to do some basic objects in both 2D and 3D grids, but I keep getting self-intersecting error messages in Gambit for 2D and when I subtract and grid volumes in 3D and run in fluent I get another error message as follows:

Quote:
Error reading "Z:\Program Files\Ansys\File Repository\z drive Ansys Fluent and Gambit Working Directory\Titan 3D tunnel with roughness and plate.msh".
and in Fluent's box I get:


Quote:
> Reading "Z:\Program Files\Ansys\File Repository\z drive Ansys Fluent and Gambit Working Directory\Titan 3D tunnel with roughness and plate.msh"...
193778 nodes.
192634 mixed wall faces, zone 2.
4116 mixed pressure-outlet faces, zone 3.
40320 mixed wall faces, zone 4.
60386 mixed symmetry faces, zone 5.
85352 mixed wall faces, zone 6.
4740 mixed wall faces, zone 7.
Error: no cells in zone, id = 0, ind1 = 1, indn = 0Reading Cells: failed while reading section 12.

any idea where section 12 would be? I have no idea what they're referencing, and there's no good Gambit gridding tutorial, unless someone can post one.

there maybe are two problems:
1. the grids for geometry doesnot complete absolutely.
2. your computer's hardware, especially RAM, isnot able to handle so many nodes.

you shuoud re-check and re-fine your mesh, reducing the quantity of grids is better.

-mAx- will become famous soon enough
Do you have any warning or error while exporting your mesh from gambit?

Copper, thank you--that seemed to work. I reduced the interval for meshing a slight bit and it read into Fluent just fine. Thanks again.
