Logarithmic gas pressure (top left), logarithmic density (top right), logarithmic Lorentz factor (bottom left), and logarithmic magnetic pressure (bottom right) at t = 0.4 for the 2D cylindrical magnetized blast wave with moderate (two left columns) and strong (two right columns) magnetization. Magnetic field lines are superposed on the magnetic pressure. We consider the Cartesian grid [ − 6, 6]×[−6, 6] with 1024 cells per spatial dimension.
