I've run into this problem a few times; it essentially means that
the calculations going on inside Type56 to resolve all the gas and
pane temperatures in your window are not converging. I have often
had success by changing the inside surface convection coefficient
calculation from "automatic" to "constant" in the window type
manager for whichever window is giving problems. A typical value for
the a constant inside convection coefficient is 11 kJ/h.m2. This is
not an ideal solution because of course the convection coefficient
changes as the window pane and room temperature change but it does
stabilize the calculations some.<br>
Also make sure that you do not accidentally have something strange
going on in the zone (huge gains, moisture loads, infiltration, or
ventilation) and that your zone capacitance is set to about
ZoneVolume*1.2*1.007*5.<br>
Kind regards,<br>
David<br>
