[TRNSYS-users] Stuck simulation

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,
Kind regards,
 David
