Left: volume integral of the square of the current density throughout the T1 (red), T2 (green), and T3 (blue) simulations. We show results for ideal (solid lines) and resistive (dashed) experiments. Right: volume integral of the square of the vorticity for the T1 (red), T2 (green), and T3 (blue) simulation. We show results for ideal (solid lines) and viscous (dashed) experiments. In each panel, we have normalised the curves using the maximum values obtained during the simulations.
