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 effectively thermal
resistance and others properties. Can I change some 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!
