I see that particles that leave the domain can be saved after they leave by enabling a flag, but it appears that their evolution at this point is frozen. It looks like a few relatively simple changes in Particles_advance may be able to continue their evolution, but I wasn't sure if evolving these particles would cause issues.</span><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">Has anyone tried to do something like this before?</span><div style="font-size:12.8000001907349px"><br></div><div style="font-size:12.8000001907349px">Cheers,</div><div style="font-size:12.8000001907349px">- James</div><span><font color="#888888"><div><br></div>-- <br><div><div dir="ltr">James Guillochon<br><span style="font-family:arial;font-size:small">Einstein Fellow at the Harvard-Smithsonian CfA</span><br><a href="mailto:jguillochon@cfa.harvard.edu" target="_blank">jguillochon@cfa.harvard.edu</a></div></div>
