Vincent,
*TRACE* UNIT 51 TYPE 56 AT TIME 2.6764166666666665E+03 ITERATION 2 CALL 13105 POST-CONVERGENCE CALL. (can you tell me what it means?)once TRNSYS converges on a solution at a given time step, the kernel calls all types once more so that they can do anything that they might need to do (update summaries, print reports for that time step, make control decisions that are not supposed to be iterative, etc.)
all of those suggest that there is something that gets stuck in an infinite loop. The only way to really track it down is to run it from the Fortran compiler I am afraid,The simulation time step is 1 minute and if I use 5 minutes it does not hang up at the same hour. Moreover I have already encountered the problem during the night, that is to say when the system is turned off (heating coils, cooling coils, humidifiers, PID's are switched off).
