[TRNSYS-users] controlling the passage to the next time steps

[pierre.jaboyedoff at effinart.ch]

In trnsys 13.1, i had (long time ago ..) modified the kernel of TRNSYS (see
below).

The reason was to be able to check if the control routine developed was
converging to the correct physical case (e.g. solar, then auxiliary etc 
).
If not then i was getting TRNSYS to restart the iteration on the same time
step until the correct control case was obtained.

 

Has anybody done something similar for TRNSYS 17.2 ?

I have started looking for this, it seems to be located between, exec.for,
trnsys.for, etc 


 

Thanks in advance,
