I have been running very large experiments that take a few days to run. Murphy's law seems to interfere through either power outages or automatic updates which can cost me a couple of days of computer time. So I found some code using autohotkey and modified it to work great with SIMIO. autohotkey is a free download and easy to use. The below code runs a loop which hits {control S} on the SIMIO window if it is open every 10 minutes.
Persistent
;run a loop 100 times saving every ten minutes if your SIMIO file is open.
loop, 100
{
;save file every 10 minutes
