Time evolution of several volume-averaged quantities for the stratified net-flux simulations with varying artificial resistivity (α_B = [0.3, 0.5, 1.0, 2.0]) at a resolution of n_x = 58. Magnetic energy (top left), kinetic energy (top right), normalized Maxwell stress (bottom left) and the total stress (bottom right). The red lines show the simulations run with TSPH and blue lines show the runs with GDSPH where the darkness of the line represents the strength of the artificial resistivity. We have smoothed the curves using a Savitzky–Golay filter, the unsmoothed curves can still be seen as very transparent curves.
