[TRNSYS-users] TRNSYS error

[David BRADLEY]

Béatrice,
   The error message is indicating that the energy balance across one of 
the walls in your Type56 (I am guessing) building is not converging. 
Specifically, the outside surface temperature of the wall is not coming 
to a stable solution. If you are using an algorithm to set the 
convection coefficient on the outside surface of your wall, make sure 
that the algorithm cannot produce a result of 0; this would indicate 
that there is NO convective heat transfer on the outside surface of the 
wall and that only the radiation matters, which is unrealistic. The 
second thing to try is that if you have variable convective coefficients 
on either the inside or the outside surface of that wall, turn them off 
and use constant values.
Kind regards,
  David
