[TRNSYS-users] Slow simulation

[Jeff Thornton]

Erik,

Did you turn on debug mode in the control cards and see where the simulation is spending all of its time?  You’ll be able to see by unit number and by type number the amount of time spent in each model.

And if I try to simulate more systems at once the cpu is more or less a multiple, so three simulations at once using about 60 % of the cpu. So what is the limitation of the computer prestanda when simulating?
