[TRNSYS-users] Error 114

[David Bradley]

Ioannis,
  I would imagine that the error is not irrelevant - it is telling you 
that one of the components in your simulation has called the TRNSYS 
moist air properties routine with properties that are not physically 
possible and that under these circumstances, the TRNSYS psychrometrics 
routine is not able solve for the state of the air. What I don't know is 
why the steam splitter and steam turbine models are calling the 
psychrometrics routine instead of the steam properties routine. That, 
however, is a question that hopefully the STEC library authors can answer.
Kind regards,
 David
