[TRNSYS-users] Getting error in simulation "automatic heat transfer calculation"

[David BRADLEY via TRNSYS-users]

Maria,

   Maybe you already did but also check to make sure that the external 
windows are not set to have an automatic calculation on the external side.

   I have run into this situation as well and I think I finally fixed it 
by turning off ALL the automatic heat transfer calculations and then by 
adding them back in a few at a time until I found the wall that I 
thought was only used as an ADJACENT wall but in fact had been used as 
an EXTERNAL wall as well. Fortunately I didn't have too many wall types 
to check.

kind regards,

  David
