mkpolytrope - make N-body model of generalized polytrope
mkpolytrope
out=out_file [parameter=value] ...
mkpolytrope generates an N-body
realization of one of Henon’s generalized polytropes. At present, only the
polytrope n = 1, m = -1 is supported.
The following parameters
are recognized.
- out=out_file
- Write to out_file in snapshot(5NEMO)
format.
No default.
- nbody=num_bodies
- Number of particles to generate. Default: 512.
- n=E_exponent
- Exponent of energy in distribution function. This can be a
real-valued expression. Default: 1.
- m=J_exponent
- Exponent of angular momentum.
This can be a real-valued expression. Default: -1.
- seed=random_seed
- Seed
for random number generator. Default: 0.
- headline=message
- Message prepended
to out_file. Default: none.
