treecode0 - NEMO frontend for the TREECODE family of programs
treecode0
[parameter=value]
treecode0 is a NEMO frontend to run any of
the TREECODE family of programs. Standard NEMO datafiles are given, converted
on the fly to "205" format, the specified TREECODE integrator is run, and
output files in "205" format are converted back to NEMO’s snapshot(5NEMO)
format.
This program works by writing a C-shell script tmpscript.pid, where
pid is the process ID (see getpid(3)
). This script is then executed via
execl(3)
, and kept in the current working directory.
Since this program
uses the following NEMO programs, they need to have been installed: stoa,
treecode*, and atos.
The following parameters are recognized
in any order if the keyword is also given:
- prog=progname
- Name of the TREECODE
program to be run. [Default: treecode2].
- in=insnap
- Snapshot input filename.
This snapshot is converted to TREEBI by stoa(1NEMO)
. No default.
- out=outsnap
- Snapshot output filename. This is the ascii output TREEBOA converted back
to snapshot by atos(1NEMO)
. No default. Note that the working directory for
TREECODE will be outsnap_dir.
- log=logfile
- Output logfile. This is the TREELOG
file. No default.
- clean=t|f
- Clean up temp files? [Default: t].
- exec=t|f
- Execute
the script? [Default: t].
- ...................... The remaining parameters are for the TREECODE ................
- text=
- Title for the
run. Maximum string length is limited by the declared string lenght in
the called fortran program. treecode2 has a maximum of 50 characters.
- nsteps=
- Total number of steps for this run [64].
- noutbod=
- Number of steps before
major output of mass,phase,phi [8].
- noutlog
- Number of steps before output
in logfile [1].
- dt=
- Integration timestep [0.03125].
- tol=
- Tolerance, the accuracy
of the treecode, also called the opening angle [1.0].
- eps=
- Softening length
[0.05].
- usequad=t|f
- Use quadrupole moments? [f].
