Rayleigh-Taylor Instability

The RT Instability…a dense fluid sitting on top of a light fluid. When slightly perturbed the light fluid rises upwards, and the heavy fluid sinks downwards. See this page for more details on the problem analysis and simulations: RT This simulation shows a single mode perturbation. It is run in 2D with a fixed grid of 100 x 300.


For this run, all parameters are the same. The grid is now 50 x 150, and there are 3 levels of AMR which yields an effective resolution that is 4x the previous run.


I realized that uniform gravity was not working properly in the first two simulations, so here is one in which it is working. Also, this simulation is a 50 x 150 grid with 2 levels of AMR. This set up could be the one to go into the test suite.



Field Loop Advection

This is from when I was first learning how to run AstroBEAR.
