Small change leads to huge difference in simulation duration

Postby Ha_Aria » Mon Jun 11, 2018 6:25 pm

I am working on a big size building model that usually takes about 3 hr of simulation to get annual results. recently I added extra water heater (radiator) to some of the group zones to solve my setpoint not met hours. These extra heaters changed my simulation duration to 14 hr !!!!
I reviewed big size building modeling recommandations article however, I still can not understand why this small change leads to huge simulation duration difference and is there anyway I can fix this problem?
I appreciate any helpful comments :)
