[TRNSYS-users] VirtualSurface

[David BRADLEY]

Karol,

  I think your picture is correct.

  The process for setting it up can be a little confusing. My 
understanding of how to set up the second case is to draw both Zone1 and 
Zone2 separated by a VirtualSurface in Trnsys3d. I assume there is some 
way of doing the same in TRNLizard but I'm afraid I'm not familiar with 
that tool. Once you import the *.idf file into TRNBuild, the virtual 
surface will disappear. You then add Zone2 to Zone1 so that they become 
two airnodes of a single zone. To do this, you open the zone/airnode 
that you're going to move and you click on the button in the upper left 
corner that looks like a u-shaped arrow.

  Since the virtual surface that separates the two airnode has 
disappeared you no longer have an adjacent surface through which to 
define the air flow coupling. Instead, you click on the "coupling" 
button in the airnode window (upper right) and define the coupling there.

best,

  David
