[TRNSYS-users] Virtual window error

[Knut Erik Enerstvedt]

 Dear Sumaila Aongya,

Try the virtual window with WinID 10001 (Basic or American library) instead.
I also get this error with WinID 1.

Best regards,
Knut Erik Enerstvedt


>Hello,
>I am simulating a building using TRNSYS 17. On the recommendation of M.
Kummert, instead of using a wall made of air to represent >hallways or lack
of a wall from a zone to another one, we changed them into virtual/non
existant windows (WinID: 0001) with tiny frames >(2% of surface area). Now,
the problem is that the simulation cannot run the model because it's
creating an error UNIT7, TYPE 56 " >iniglasdata: value negative or greater
than 1 for nonvisual absorption W4_front was found after fitting for
Window-ID.  1: abs_nonvis= >-0.008717874 at angle= 0."  I get this error
with horizontal and vertical windows but if I simulate the same
building with real windows i.e. >7433 instead of virtual ones, it works
perfectly.

>We changed to virtual windows because it's supposed to represent more

configurations so this error doesn't come back? Should I just keep the air
walls, since the difference in properties are >almost negligeable?

>Can you help me with this?

>Thanks!
