The runs were performed on the 20 processor (Intel Pentium IV 2.2GHz) Beowulf-type cluster built by the University of Rochester Theoretical Astrophysics Group (Alexei Poludnenko and Andy Cunningham). All the animations below represent the logarithm of density.

For further details on the simulations below see the publication.
Runs have the following parameters :

!!! Note: the parameters are the ones used in the simulations. Since the simulations were adiabatic with an ideal gas EOS, the scalings for temperature (and therefore pressure) are somewhat different from the ones to be used in the real-life experiment. In particular, temperature of the unshocked interclump material was assumed to be 300 K. That also affects the estimate of the shock and post-shock Mach number.
