Hi, the memory usage is not saved to the netCDF-file, so you can only call this method/plot directly after making the simulation.
Perhaps in the future it might be included in the netCDF-file.

Hi Knut, I figured that this was the case. I added o.plot_memory_usage() to my scripts, so that the plots will be made while the simulations are still in memory. Thanks.
