The MHD blast wave was computed by numerous authors, we performed the test case following the same setting in Gardiner & Stone (2008) using Scorpio. The test case is similar to the 2D HD blast wave problem under low $\beta$
ambient medium. The simulation setting is summarized in the following table.

plane, similar features as Figure 8 of Gardiner & Stone (2008) are captured by Scorpio. A shell of a fast and weakly compressive shot dominated by the magnetic field radiating outward is clearly shown. Besides, at the two ends of the sphere parallel to the magnetic field, dense shells propagate parallel to the field direction separating the cold surrounding gas and interior hot gas are also shown by the two red crescents.
