<p>Dr. Sarmouk,</p>
<p> I would recommend finding surface 443 in TRNBuild and then
looking at its external convection coefficient. If the external
convection coefficient is set to be variable then as a test, set
it back to a constant and see if the error goes away. You can also
look at whether the wall is very highly thermally conductive and
whether it has a particularly high solar absorptance on its
outside surface.<br>
</p>
<p>kind regards,</p>
