[TRNSYS-users] variable time step?

[Fred Betz <fbetz@aeieng.com>]

I'm at a conference this week and someone mentioned using a variable time step in simulations (not TRNSYS) and I was wondering if this was possible in TRNSYS. 

I know you can make the time step a variable in the deck. 

I could see using this if you want to carefully control startup and shutdown of a device, but while the device is running or not running, you could have a larger time step. This would speed up the overall run time. 

It would probably play havoc on the printegrator. 

Just wanted to start a discussion about this topic to see if it's been done successfully and when.
