[Simergy-users] Functional Plenum Zones

I'm just getting started and am trying the latest Simergy Pro. Can anyone tell me if return and supply plenum zones are really supported?

If so, is there some clear set of procedures for getting from the geometric "ceiling plena or voids" to airflow through them?

As far as I can tell, only the  ASHRAE System 7 model shows plenum zones under the "spatial zones" branch of the project tree. However none of these are referenced in the Zone HVAC Groups,  which requires an entry of a "shared" or "dedicated" plenum component between the zone outlet and the "supply" inlet. But when I've tried this, Simergy itself hangs or the model doesn't run. The model as supplied runs, but the "plena" are just simulated as unconditioned zones/spaces when I examine the IDF.

I tried importing a E+ 8.0 sample idf with floor/supply and return plenums, and that didn't go anywhere either.
