[TRNSYS-users] Outside temperature iteration

[David BRADLEY]

Dr. Sarmouk,

   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.

kind regards,

  David
