Magnetic rotor test 1D slices along y = 0.5 (left panels) and x = 0.5 (right panels) of (from top to bottom) rest mass density, gas pressure, magnetic pressure, Lorentz factor, and magnetic field divergence normalized to the magnetic field intensity, at time t = 0.4. We show results from the MFM run (red triangles), MFV (orange circles), and from a fixed particle position one (black squares) for reference.
