Noh shock wave
Comparing simulations to transprot models whose solutions are known allows verification as well as an analysis of mesh refinement. In this example with the Noh problem, a shock wave is illustrated (long dashes) by the higher density inside the 0.2-cm wave front and a low density outside. One can see that increasing the resolution by decreasing the grid spacing, Δx, demonstrates convergence of the numerical results to the exact solution.
