    7070== 1D Jet Simulations ==
     71The set up for these simulations is very simple.  The grid is initialized with an [wiki:AmbientObjects ambient object] and a [wiki:WindObjects wind object].  Here are the initial parameters:
     72{{{
     73Ambient:
     74density = 1000 particles/cc
     75velocity = 50 km/s
     76temperature = 1000 K
     77By = 30 uG
     78
     79Wind:
     80density = 1000 particles/cc
     81velocity = 50 km/s (but with a sinusoidal perturbation)
     82temperature = 1000 K
     83By = 30 uG
     84
     85Global Data:
     86Domain length = 0.4 pc
     87Final time = 0.01 s
     88Resolution: 200 cells in x, 2 cells in y, 2 levels of AMR ===> effectively 800 cells in x
     89}}}
     90The ambient is acting as the unperturbed jet, and the velocity perturbations come from the left edge of the domain.  The perturbations range from 0 to 100 km/s, and the period can be adjusted.  The first simulations went through 10 periods, while the second set of simulations only went through 5 periods.
