Name

runmond - frontend to the rmond program

Synopsis

runmond [parameter=value]

Description

runmond is a frontend to N-MODY, a parallel code for collisionless N-body simulations in modified Newtonian dynamics (see also Ciotti, Nipoti, Londrillo 2006) The input file is a standard NEMO snapshot, except that all masses are taken equal to that of the first particle. All output is accumulated in a run directory, as specified with outdir=. See the detailed description in the N-MODY users guide for their meaning. Particle positions and velocities are dumped one per snapshot, and can be converted back to NEMO files with modysnap(1NEMO) .

Parameters

The following parameters are recognized in any order if the keyword is also given:
in=
Input snapshot. No default. All masses are assumed equal the first one found in the snapshot. Conversion to the format required by rmond is done by snapmody(1NEMO) . No Default.
outdir=
Run directory in which all files produced by N-MODY are placed. No default.
out=
Output snapshot file name if to convert the moutXX.bin files back to a nemo file. Unless an absolute pathname is given, this file is placed in the outdir. Default: not used.

Examples

Benchmark

The default 2,048,000 particle distribution takes about 32 minutes to integrate 1 timeunit.
