[TRNSYS-users] Stuck simulation

[David Bradley]

Vincent,
  It is a bit hard to say without running your simulation from the 
debugger. I have run into some rare cases when the code got into an 
infinite loop internally. The fact that the problem happens at different 
times when you start it at different spots suggests that this might not 
be the case, however. Have you tried activating the TRACE function to 
see if you can see a non-convergence in the inputs and outputs before it 
hangs up?
Kind regards,
 David
