[TRNSYS-users] controlling TRNSYS iteration and next time step

[Diego Alejandro Arias]

Hi Pierre,

TRNSYS checks that all components have converged during each time  
step, by making sure that the values of the array OUT for each  
component have stopped changing (within tolerance).  You do not need  
to modify the kernel routines, but just make a new Type that changes  
an output value until it decides that all the conditions are OK, and  
therefore it is allowed to go to the next time step.

Please take a look at Type22 (iterative feedback controller). It takes  
advantage of the way that TRNSYS decides whether the simulation has  
converged during the current time step or not.

I hope this helps.
Regards,

Diego
