Problems with the interior zone type
 

Hi,

I have in my geometry two volumes together and both are the same fluid, I called the wall in between these 2 volumes "interior" zone type, when I exported this domain to fluent I receive the following message:

1) Warning: Inappropriate zone type(interior) for one-sided face zone 1

2) Error: Cannot change IV-1 ( this is the name of the interior face) to interior because ther is only one adjacent cell thread.

Can anybody help me understand these messages? what should I change in my geometry?

Thanks in advance

Re: Problems with the interior zone type
 

The problem is that the volume mesh is only attached to one side of the face. There are two possible causes. The first is that when you were assigning your interior bc, you accidentaly selected a face that you shouldn't have (a face that should have been part of a wall, a pressure inlet, a pressure outlet, etc...). The other cause (and the more likely cause) is that there is actually two faces between the volumes. It depends on how you made the two volumes. If you split a large volume to create two volumes, then you might have forgotten to turn on the "connected" option. If you created the two volumes separately, then you never connected the faces where the two volumes touch. To fix this, you can either connect the faces where the volumes touch, or you can define each side as a separate "interface". Then in Fluent you go to Define->Interfaces and connect the two interfaces there.

Hope this helps, and good luck, Jason
