Sod test: viscosity at different resolutions. Profiles of the viscosity in logarithmic scale for the special-relativistic Sod test at \(t=0.6\), computed with EL5 at different resolutions (parametrized by the number of points on the x axis). The four peaks correspond to the four different features of the solution, i.e., from left to right, the edges of the rarefaction wave, the contact discontinuity and the shock (vertical dashed lines highlight their location). As the resolution increases, they tend to delta functions.
