multi-blocks & boundary overlaping

It is stated in the Fluent online help that it is possible to use multi-block griding scheme by overlaping the interfaces of different cell zones. For complex geometry, it may need numerous blocks in order to generate structured meshes. Did anyone try it before in Fluent and how about the results? Thanks.

You can certainly create (in Gambit) a multi-block mesh with one common interface btwn two blocks. I am not sure what you mean by "overlaping the interface". You can't have two edges or faces that are overlapping.

Thank you for your reply, LW
Multi-block mesh means that a computational domain is decomposed as several blocks, which are meshed separately in different mesh files and merged together using another software like Tgrid, although the grids on the boundaries between the adjunct blocks are not matched. This method provides the flexibility while a complex geometry is encountered. I tried the method before. But, negative volume errors were indicated in Fluent, after I used grid interface definition to define the overlapping boudaries. Looking forward to your comments. Thanks. |

I always use confirmal mesh at the interface. So, didn't encounter the problem like yours. You may have to talk to your support for this one.
Good Luck, LW |
