Three-dimensional Euler-equations for an ideal gas (Air with   = 1.4)
Wave propagation scheme with Minmod wave-limiter and transverse wave propagation
Calculation of 792 time steps with CFL-No.  0.9  to   tend = 0.04 s.
AMR-computation with a coarse grid of 40 x 40 x 40 cells. 2 levels with refinement factor 2 are used. Finest level corresponds to 160 x 160 x 160 grid (4 M cells).
Number of cells increases continuously from 1.1 M up to 3 M.
71 h real time on 7 nodes Pentium III-450 MHz (nonadaptive  190 h)



The computations are included in the following paper:
