[TRNSYS-users] Virtual window in TRNBUILD

[Marcello Caciolo]

Dear TRNSYS users,



I am trying to model a zone with an opened window in TRNSYS 16. For the 
thermal model, I use the type56 with a window of the type: "Virtual 
(open or nonexistent) Window" (WINID 1) from TESS Library.



Unfortunately, when I start the simulation, I get the following error:



"Une valeur négative ou supérieure à 1 a été trouvé pour l'absorption 
non visuelle W4_front pour la fenêtre no 1 : abs_nonvis = -.0008717874 à 
l'angle = 0"

(A value negative or greater than 1 was found for nonvisual absorption 
W4_front for Window-ID   1 : abs_nonvis = -.0008717874 at angle = 0)



I see that other people reported this problem in this forum, but I have 
not found any solution.



Do you know how to solve this issue?



Thanks in advance for your attention.



Best regards,



Marcello CACIOLO
