Excluding cad from dump/stl

Submitted by rahulsoni on Sun, 10/13/2013 - 08:42

I have two cad files in my simulation. The one is auxiliary just works as splitter and need not to be visible in final results. I know I am using line "dump dumpstl all mesh/stl 200 post/dump*.stl" in my script which applies to all meshes, and by changing the group-ID the issue can be handled. But I don't know how to assign group-ID to stl files (or mesh groups).

Anyone please help...
An example would be really appreciable.

Thanks in advance.
