long simulation batch (or parameter sweep)

Please login with a confirmed email address before reporting spam

I need to do a long simulation where I vary the values of a couple parameters.

I've read about doing long simulations in steps to avoid large files. This is perfect for my situation as I'm only interested in the variation over one day, but I need to let the system equilibrate over many days. I plan to delete the files for days before the system has equilibrated.

Is there a way to combine this approach with a batch or parameter sweep? Namely I don't want to go in and change the initial value to "current solution" 50 times if there's a way to do it just once.

I need to run the full simulation for each parameter combination which should be possible with batch sweep, but I haven't found a way to also break each simulation in the batch sweep into steps to avoid large files (one full simulation is ~30GB when not broken into steps).
