Blast-wave test: solution profiles. Profiles of the rest-mass density (left), velocity (center) and pressure (right) for the special-relativistic blast-wave test at \(t=0.4\). The solution is computed on a grid of 800 points. The inset in the density panel magnifies the blast wave, showing also the exact solution in black. Inversion failures due to oscillations when using the EL5 scheme spoil the quality of the solution.
