Hi Antoine,
adjacent windows between airnodes inside of one radiative zone
are not possible. Normally in such cases there are fully
transparent openings
for that you won't need a window definition because even without this
window all walls are in radiation exchange.
Would be interesting
how you got this defined in order to avoid this in the
next TRNBUILD version.

[mailto:antoine.gautier@solamen.fr] On the same
topic... I am
trying to model a fully glazed wall with fully transparent window between the 2
airnodes to account for radiative transfers. When I
save the building file I get the message: “.inf etc. generated
successfully”. However
when I launch the simulation I get the message in attachment which appears in
TRNEXE window. If you
check the .inf file you will notice that adjacency is well defined for surfaces
9, 11, 12 and 13 despite the previous message error. Eventually
the simulation goes on but the results tend to convince me that radiative
transfers are not correctly calculated between the 2
airnodes. Do you
have any idea to solve this problem? Thanks a
lot. Regards -- Antoine

[mailto:antoine.gautier@solamen.fr] Dear
all I
understand from the user manual §5 that longwave radiation exchange is not taken
into account between 2 airnodes of the same zone under standard (starnet) or
“one node” radiation mode. Could you
please confirm my understanding? Then what
is the best strategy to transfer internal gains and radiative heating flux (e.g.
from active layer) to the other airnode of the same zone when not using 3D
data? Thanks a
lot for your help. Best
regards -- Antoine
