Time-averaged values of several quantities for all our unstratified, zero net-flux simulations with standard box size (L = [1.0, π, 4.0]) and resolution n_x = 96. From the top left to bottom right: magnetic energy density, Maxwell stress, normalized Maxwell stress, ratio between Reynolds and Maxwell stresses, total stress, ratio between radial and total magnetic field energy. The x-axis shows the time-averaged effective Prandtl number of the simulation. For some quantities we have plotted the total time average (shown in green), the time average of the turbulent component (shown in orange) and the time average of the mean component (shown in blue). The circles represent the simulations where we have adjusted the strength of the artificial resistivity, while the star symbols represent the simulations where we have adjusted the artificial viscosity.
