You could edit the final sim volume prims in sops with a volume mix and 
another volume to carve out the area of the prims you don't like.

It is emanating from a tube, and even if the tube geometry is not visible, the tube gets filled with smoke as it emanates the billowy smoke I'm looking for.  I would like to see the smoke emanating from "a void" as it were.
