Re: [EnergyPlus_Support] comis network error

["Michael J. Witte" <mjwitte@xxxxxxxx>]

As it says in the error message, there must be at least one external node.  Add 
a small exterior crack in one of the zones.  Also, be careful with internal 
doors and windows.  For heat transfer there must be two adjacent surfaces, one 
in each zone, but COMIS only needs one opening between the two zone, not two.
