[TRNSYS-users] Messages, warning and notices in TRNSYS ( message 441)

[David BRADLEY]

Sandeep,
   TRNSYS has three levels of notifications: "notices" are for 
informational purposes only, "warnings" are a potential issue and should 
be investigated further to determine whether they are serious or not, 
and "fatals" are errors that will stop a simulation immediately. If you 
are getting a non convergence warning for 10 timesteps in an annual 
simulation then there is nothing to worry about. If you are getting non 
convergence warnings for 10 timesteps out of a 10 timestep simulation 
then it is an issue that needs to be addressed.
kind regards,
  David
