| 71 | The 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 | {{{ |
| 73 | Ambient: |
| 74 | density = 1000 particles/cc |
| 75 | velocity = 50 km/s |
| 76 | temperature = 1000 K |
| 77 | By = 30 uG |
| 78 | |
| 79 | Wind: |
| 80 | density = 1000 particles/cc |
| 81 | velocity = 50 km/s (but with a sinusoidal perturbation) |
| 82 | temperature = 1000 K |
| 83 | By = 30 uG |
| 84 | |
| 85 | Global Data: |
| 86 | Domain length = 0.4 pc |
| 87 | Final time = 0.01 s |
| 88 | Resolution: 200 cells in x, 2 cells in y, 2 levels of AMR ===> effectively 800 cells in x |
| 89 | }}} |
| 90 | The 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. |
