Resuming an interrupted run

[ah-dinh]

Hi,

Is there a way to periodically save the progress of a run and resume it at a later time? I'm doing large runs over the span of many weeks that sometimes get interrupted due to system shutdown and other issues. The only solution I can think of is breaking the long run into shorter segments and re-initialize the particles from their previous location. Before I attempt to implement that, is there a built-in checkpoint/recovery method or an easier work around for me to resume an interrupted run?

Yes, you can use the particleset.from_particlefile() method, see here for the API reference, and the unit test below for an example implementation https://github.com/OceanParcels/parcels/blob/5578e4bd7863be620eac6fefbb12939755959a11/tests/test_particle_sets.py#L85-L115
