[EnergyPlus_Support] VAV w/ PIU system takes a lot to run

Hi all,

I am currently running a very large model (an office tower with about 170 zones) using a VAV with PIU fans and have been experiencing an extremely time consuming running with it. Simulations last about 4 days, in a good computer, because of the PIU node errors in the post processing. Thing is when I abort the simulation just after the conclusion of the annual running (when the post processing is starting), the HTML file I configured in the IDF is not generated. 

Any help on how I can avoid the post processing in the running in order to get results faster? Or anything else I can do?


Thanks all,
Johnny
