Density (left panels) velocity (middle panels) and pressure (right panels) for the Newtonian strong shock test. We show both the analytic solution (solid line) and the numerical solutions obtained with different numerical schemes (dots). The resolution is Δ¹ = 1/100 and the timestep is Δ⁰ = 0.002 for all the runs. Note that the numerical solution is not down-sampled and corresponds to a rather coarse resolution.
