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.<br>
kind regards,<br>
