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.
See also ZENO’s General Spherical Profile
for another generalization to create models.
The following parameters
are recognized in order; they may be given in any order if the keyword
is also given. Use --help to confirm this man page is up to date.
- 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.
