Resistive shock tube problem. The upper panel shows the density and the lower panel shows the y-component of the magnetic field at the final time t = 0.55. The blue solid line is the case η = 0, the dotted cyan line is the case η = 0.01, the green dashed line is the case η = 0.1, the yellow dot–dashed line is the case η = 1, while the red double-dot–dashed line is the case η = 1000.
