    33The Rayleigh-Taylor instability arises when a fluid pushes against another fluid of different density.  The simplest way to imagine this situation is to consider a heavy fluid sitting atop a light fluid. The system is in hydrostatic equilibrium with gravity pointing downwards.  A small perturbation at the interface between the two fluids will disturb this unstable equilibrium, and the heavy fluid will sink while the light fluid rises.

     6The problem setup is adapted from the Athena test suite page: [http://www.astro.virginia.edu/VITA/ATHENA/rt.html]
    77This page has information on both 2D and 3D simulations, Hydro and MHD, but the 2D Hydro case is the relevant one here.
