| maxstep |
maximum number of time steps
- for a normal run (e.g., 48 hrs), this is a large integer, e.g., maxstep = 10000000
- for testing/debugging it can be set to a smaller number, e.g., maxstep = 10 |
|
|
1000000 |
|
|
| hrmax |
runtime (hrs)
- maximum runtime is hrmax = 168 (7 days)
- nominal minimum runtime is hrmax = 36
(it takes ∼ 12 hrs for the ionosphere to develop) |
|
|
48. |
|
|
| dthr |
output cadence (hrs)
- nominal output cadence is dthr = 0.25 (15 min)
- for testing/debugging it can be reduced to output data more often |
|
hours |
0.25 |
|
|
| hrpr |
time data starts to be output
- nominally hrpr = 0 and data is output from beginning of the run
- alternatively, if hrmax = 48 and hrpr = 24, data is output starting after the first day
(this reduces the size of the output files) |
|
hours |
24. |
|
|
| dt0 |
maximum time step (sec)
- should be in the range 2 - 8 sec
- the larger dt0, the faster the code runs in general
- however, depending on geophysical conditions and the grid, the code can give un- physical
results if initially too large (e.g., dt0 = 8) |

| tvn0 |
modifies the magnitude of the neutral wind speed
- nominally tvn0 = 1
- use caution when changing, e.g., tvn0 = 2 will double the neutral wind speed |

|
|
| tvexb0 |
modifies the magnitude of the E × B velocity
- nominally tvexb0 = 1
- use caution when changing, e.g., tvexb0 = 0 will set the E × B drift to 0 |

| snn |
multiplier for neutral densities
- the 7 entries correspond to the 7 neutral species in parameter mod.f90
- for example, if snn = 1.,2.,1.,1.,1.,1.,1., then the oxygen neutral density is doubled |
|
|
1.,1.,1.,1.,1.,1.,1. |
|
|
| stn |
multiplier for the neutral temperature
- this will change the ion temperatures because of ion-neutral coupling - it will not change the scale height of the neutrals |
