I'm interested in comparing the state of a simulation during various times of running - that is, I'd like to view the result data from the simulation monitors at different times during the simulation runtime. 

Currently, I do this by running a sweep where I change the runtime stop conditions (either 'simulation time' or 'autoshutoff min'). I was curious if there was some way to do one of the following:

• Continue running a simulation that has finished running (saving snapshots when simulation ends its run).
• Manually pausing and saving a copy of the simulation during its run, then continuing. If there is a way to do that programatically, that could be an advantage. 

Thanks,

You can use time monitor to record data at a specific time step:

Thank you so much for the clarification, I had yet to use this monitor. It does exactly what I was describing.

Is it possible to increase the time interval between snapshots in the TimeMonitor, without affecting the simulation accuracy (without changing dt)?

Time step value should use the default one in general. Reducing this value will lead slightly less accuracy, counter intuitively.

In the time monitor, you can downsample the signals to be recorded:

The default value is 10. Although in theory the minimum value is 2, since we do not want to recocer the signal, this value can be smaller, such as 0.1 to record much large time laps.
