fix gran/diag command :h3
|
|
|
|
[Syntax:]
|
|
|
|
fix ID group-ID gran/diag nevery file layer :pre
|
|
|
|
ID, group-ID are documented in "fix"_fix.html command
|
|
gran/diag = style name of this fix command
|
|
nevery = compute diagnostics every this many timesteps
|
|
file = filename to store diagnostic info in
|
|
layer = bin size in z-dimension (3d) or y-dimension (2d) :ul
|
|
|
|
[Examples:]
|
|
|
|
fix 1 all gran/diag 1000 tmp 0.9 :pre
|
|
|
|
[Description:]
|
|
|
|
Compute aggregate density, velocity, and stress diagnostics for a
|
|
group of granular atoms as a function of depth in the granular system.
|
|
"Depth" means the z-dimension for a 3d simulation, and the y-dimension
|
|
for a 2d simulation. The results are written to 3 files named
|
|
file.den, file.vel, and file.str. The bins begin at the bottom of the
|
|
system and extend upward with a thickness of {layer} for each bin.
|
|
The quantities written to the file are averaged over all atoms in the
|
|
bin.
|
|
|
|
[Restart, fix_modify, output, run start/stop, minimize info:]
|
|
|
|
No information about this fix is written to "binary restart
|
|
files"_restart.html. None of the "fix_modify"_fix_modify.html options
|
|
are relevant to this fix. No global scalar or vector or per-atom
|
|
quantities are stored by this fix for access by various "output
|
|
commands"_Section_howto.html#4_15. No parameter of this fix can be
|
|
used with the {start/stop} keywords of the "run"_run.html command.
|
|
This fix is not invoked during "energy minimization"_minimize.html.
|
|
|
|
[Restrictions:]
|
|
|
|
This fix is part of the "granular" package. It is only enabled if
|
|
LAMMPS was built with that package. See the "Making
|
|
LAMMPS"_Section_start.html#2_3 section for more info.
