Evolution of the rate of change of the total energy, incoming fluxes, sources, and sinks for the reference simulation. The blue curve indicates the change in total energy over time, given by the sum of internal, kinetic, magnetic, and gravitational energies of the system, plotted as functions of time, before the onset of the instability. The red curve represents the sum of the total fluxes, energy sources, and sinks as a function of time before the onset of the instability. The closeness of the blue and red curves demonstrates the approximate energy conservation in the domain. The dashed black curve depicts the Poynting flux, which is the dominant flux and adds to the magnetic energy.
