Thermal instability in three dimensions

NONLINEAR THERMAL INSTABILITY IN THREE DIMENSIONS
Setup: Initial conditions: uniform gas distribution in a box; zero velocities Periodic boundary conditions Isobaric density perturbations (3D PSD power index -3) Equilibrium radiative cooling function Constant volumetric heating rate proportional to the gas density Handouts: Plate 1 [GIF \| PS] Plate 2 [GIF \| PS] Plate 3 [JPG \| PS] Plate 4 [JPG \| PS]			Alexei Kritsuk & Michael Norman		Numerics: Unigrid 128^3, 256^3 + AMR Zeus/PPM_DE hydro solvers Explicit split scheme for the source terms Code "enzo" Parameters: Box size Initial gas temperature & density Heating rate Gas metallicity
Most of the movies on this page are in MPEG-1 format. Moyager by Gromada.com is our suggested Windows player (freeware; supports FLIC, MPEG, HAV, JPEG, PNG...). We recommend a frame rate of 10 fps. For better quality playback under UNIX/Linux we suggest to use mpeg_play with these options: -dither color -framerate 10
