<DIV><FONT face=Arial size=2><SPAN class=624240715-10112010>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.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=624240715-10112010>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?</SPAN></FONT></DIV>
