Rayleigh-Taylor Instablity with radial gravity

Gravity is directed inwards and the initial density profile is exponentially varying with a jump discontinuity to higher density along a sinusoidally perturbed circular interface.

Four times are shown, starting from upper right image and going clockwise.


Computed on a 120x120 grid (one quadrant) using CLAWPACK with the quasi-steady wave-propagation algorithm, by Derek Bale.
