A circular shock-wave expands in an enclosed box. The reflected shocks interact in a complex manner. This example demonstrates basic adaptive functionality. See three-dimensional analogue.

- Wave propagation scheme with Minmod wave-limiter and transverse wave propagation
- Calculation with CFL-No. 0.8 to time t=0.5
- AMR-computation with a coarse grid of 150x150 cells

2 grid levels:

- Calculation of 196 time steps
- 1 levels with refinement factor 2 is used .
- Finest level corresponds to 300x300 grid (90 K cells)

3 grid levels:

- Calculation of 199 time steps
- 2 levels with refinement factor 2 and 4 are used .
- Finest level corresponds to 1200x1200 grid (1.4 M cells)
