Thomas,<br>
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>
Kind regards,<br>
David<br>
