<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Hi all,<o:p></o:p></p>
</div>
<p class="MsoNormal">I designed with google sketchup 2 boxes, 1m3 each. Those two boxes are adjacent to each other.<o:p></o:p></p>
</div>
<p class="MsoNormal">I set up the adjacent surface between both as a virtual surface, expecting that the two airnodes would be linked to each other (air motion link).<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I assumed that if I set up a ventilation rate in one airnode, the other airnode would be affected, and the two air temperatures would be really close to each other. Because I assumed that thanks to the virtual surface, the two airnodes
would act like one airnode.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">However there is not such link between both according to the air temperature result.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Therefore, I coupled the two airnodes in the TYP56, but i'm surprised that I have to set up a ventilation rate between the airnodes.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Also, I dont understand why there are "upper" and "lower" configurations.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Finally, I tried to couple the two airnodes using TRNFLOW, but when I use "large opening", nothing appear on the left frame, which still shows "undefined". Thus I get an error when I try to close TRNBUILD.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I think I don't use TRNFLOW or the coupling option correctly. Can someone help me or direct me to a tutorial so that I can learn how to couple the two airnodes properly?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Thanks a lot in advance<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Regards<o:p></o:p></p>
