Shock tube problems are widely used for code benchmarking since they directly probe the solver's ability in resolving elementary waves and their propagation. In addition, numerical results can be compared with analytical solutions.
Here we provide a simple suite of shock tube for the relativistic hydro module, by following Mignone & Bodo (2005).
The first four configurations correspond to Problem 1-4 of Mignone & Bodo (2005):
Test | rho | vx | p | Gamma |
---|---|---|---|---|
1L | 1 | 0.9 | 1 | 4/3 |
1R | 1 | 0.0 | 10 | - |
2L | 1 | -0.6 | 10 | 5/3 |
2R | 10 | 0.5 | 20 | - |
3L | 10 | -0.6 | 40/3 | 5/3 |
3R | 1 | 0.0 | 0 | - |
4L | 1 | 0.0 | 1.e3 | 5/3 |
4R | 1 | 0.0 | 1.e-2 | - |
Conf #05 and #06 are equivalent to the first two, using the entropy equation. Results are shown in the four figures below:
