The example I am thinking of involves reaching the steady-state of a high-Q photonic crystal cavity and then subsequently varying the intensity over different runs. Reaching steady-state even in a res=12, 21x40 2D experiment took nearly 150k meep-time units for a large-Q (harminv reported around 50,000). The simulation included a photonic crystal waveguide and thus did not have symmetries. Thus, saving the steady state would be advantageous here. I'm not familiar with software checkpoint utilities. I'll check into them and see if they'll do the trick.
