    22== Problem Background ==
     3The 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.
