I have a complex flow domain which i have subdivided in to many parts in Solidworks. I imported the spitted model in to ICEM 13.0. In ICEM, I created a block and then spitted it to match with my flow domain. I could able to generate full hexahedral mesh for my flow domain, but I have a Problem in exporting mesh. The problem are
1. Each of my boundary surface is a combination of several small surfaces, since I had spitted my flow domain in solidworks. When I try to export the mesh to fluent, In fluent it is giving different name for each small surface(Boundary surface). Example:Shroud in diffuser is not a single surface instead it creates shroud1, shroud2, shroud3........

2. Since I had splitted my flow domain in to several small volumes,what should i do with the interface surfaces since they also show in boundary conditions in ICEM. When I export to fluent they also show up in fluent

Hi Sujan,

when importing the geometry the first thing you should do is to put together in a single part the surfaces who are connected together and share the same boundary (as a rule of thumb).

The interface surfaces should be set up as "interior"

Hope it helps,

Rob
After you've done this you'll have to set up a boundary condition for each part, not for each surface.

Thanks Rob

I have a question with repair geometry. When i try to repair geometry i get yellow, green, red and blue lines. Is there any way to delete yellow and green lines.

Hi Sujan,

normally I just delete green edges (but this really depends on the kind of geometry you have).
To merge disconnected edges you can find a tool called "merge/stitch edges" in the repair geometry tab.

follow the guide for seeing which kind of stitching is better for which cases.
Hope this helps!

Cheers,

Rob
