Re: [EnergyPlus_Support] If there's no surface between two zones.

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

You are correct.  If there is no surface defined, there will be no 
exchange between the two zones.  CROSS MIXING is a good solution for 
this case.  The difficult thing it to determine what the flow rate 
should be for CROSS MIXING.  I would recommend trying a range of 
values to determine how sensitive the results are to this value.

I do not know of a way to model an air curtain in EnergyPlus.
