Internal surfaces for post-processor.

cfd guy

Hi everyone,
I use to make my meshes in ICEM HEXA and then import them into CFX-5-BUILD. I can define my domain and subdomains as I wish. Every boundary condition (2D faces) previously defined in ICEM are exported and I can choose which one will be an external BC (e.g. inlet, outlet, opening, etc...). However I can't do an internal boundary condition, with exception of thin walls, like a USER-2D patch in CFX-4. By now, my intentions are just for post-processing only. Once CFX-POST will bring the default objects, i.e. the subdomains, the default boundary (external wall) and the external BC's (inlets, outlets, etc...), I won't be able to choose the internal boundary which is available in CFX-BUILD but not available in POST. So, which BC can I set to enable these internal surfaces for post-processing intentions?


Thanks in advance, cfd guy
