hi all,
i made domains but when i want to assemble block it does not assemble the domains to make a block although it is a close volume and just saysInfo: 0 blocks created, 8 domains unused):mad
maybe it would be important that 6 parts of domains have structure mesh and the rest of domains have unstructure mesh.
and all of my conectors have 155 nodes
sorry i cant post my case because it is 46MB
best regards

Hi Saeed:

Can you show which domains you are trying assemble into a block? For instance, is the planar domain inside the cone part of the block face? If so, you will have to add it as a baffle face.

Is there a domain on the base of the cone that forms a closed volume?

Thanks,
Rick

Dear rick:
thanks you for response i just handled that issue by using an other type of Geometry but the new problem is: in my new geometry there is some holes that i meshed them all but now when i want to set BC for them the software can recognize them in (Set BC)panel what should i do? is there any way to set BC for them?

Hi Saeed:

I can't tell from the pictures, but are the domains in the holes used in more than 1 block? That is, is there a block inside the cone and another block outside the cone with the hole domain shared between them?

If that is the case, you can choose the Select Connections checkbox in CAE, Set BCs to be able to select them. By default, Pointwise assumes you want those interblock domains to be connections between the 2 blocks.

If that is not what is going on, please send some more information, like maybe a screen showing the CAE, Set BCs panel, CAE solver selected etc, and a picture of the List showing the domains.

Thanks,
Rick

One caveat to Rick's suggestion...

If you do assign a BC to a blk-to-blk connection domain, all the points on the domain's interior will be "inflated." This means a distinct point will be exported for each side of the domain. These inflated points will be coincident (same xyz value) but topologically distinct! You can think of the inflated domain as an infinitely thin wall.

However...

If you export using the Fluent solver (CAE / Select Solver...), you can set these connection domains to one of Porous Jump, Fan, or Radiator. These special Fluent BC types are NOT inflated at export and are written to the .cas file as a named set of faces.

hi friends ,
dear Rick and David; thanks for your great help and nice hints, i had the same problem as rick mentioned
