I think you might want to look back at your window data - as you can
see from the warnings leading up to the one that you highlighted,
Type56 is not able to converge on a window pane temperature (it has
calculated the pane temperature as "non a number" (NaN).) One thing you
might try to do is to turn off any automatic heat transfer coefficient
calculations on your windows. Usually, it is not a problem but for
certain windows that have window pane temperatures that are sensitive,
that heat transfer coefficient can change dramatically from one
iteration to the next and cause problems converging on a pane
temperature.<br>

<pre wrap="">Hello, Trnsys users.
I got some strange errors from Type56 while performing a simulation (see
attached picture). Does anyone know how to fix them? Your reply is
appreciated.
