Name

mkmestel - make a finite Mestel disk

Synopsis

mkmestel out=snapshot [parameters=values ...]

Description

mkmestel creates a Mestel disk (cumulative mass increases linearly with radius). Particles orbit clockwise, and can be given some initial velocity dispersion through the user supplied Toomre parameter.

snapmass(1NEMO) and snapcenter(1NEMO) have to be used if for some reason the user want finite mass particles and a perfectly centered set of particles.

Parameters

The following parameters are recognized in any order if the keyword is also given:
out=out_file
The data are written to this file in SnapShot(5NEMO) format [no default].
rcut=max_disk_radius
Cutoff radius of disk. [Default: 1].
ndisk=num_bodies
Number of disk particles [default: 2048]
Qtoomre=Q
Toomre’s stability parameter, which scales the velocity dispersion in the disk. [1]
seed=random_seed
Use random number seed. [default: 0].
headline=message
Text headline for output file [default: not used].
