I use File Cache to save a volume simulation that I'm working on.

I did half of the simulation but had to abort. Now what is the best way to start from the place I was before?
I tried entering frame 30, but then it redid the whole simulation up to frame 30 which took a lot of time.

I guess the pyro could not calculate correctly because it did not know the status on frame 28 so it had to redo the whole thing.

One way could maybe be to cache to disk the Simulation node? That way the simulation is cached, and then it would be easy to cache the final result. with the File Cache.
Thoughts?

you can only resume from .sim files saved directly by dopnet as they contain full simulation state (not just isolated geometry of specific dop object as your File Cache)

.sim files can be really large, however you can use checkpointing with rolling amount of trailing N checkpoints with arbitrary spacing to allow you to resume long sims in case of creashing
