fix lb/pc command :h3
[Syntax:]
fix ID group-ID lb/pc :pre
2013-11-08 04:25:37 +08:00
ID, group-ID are documented in the "fix"_fix.html command
lb/pc = style name of this fix command :ul
2013-11-08 04:17:04 +08:00
[Examples:]
fix 1 all lb/pc :pre
[Description:]
2013-11-08 04:25:37 +08:00
Update the positions and velocities of the individual particles
described by {group-ID}, experiencing velocity-dependent hydrodynamic
forces, using the integration algorithm described in "Mackay et
al."_#Mackay. This integration algorithm should only be used if a
user-specified value for the force-coupling constant used in "fix
lb/fluid"_fix_lb_fluid.html has been set; do not use this integration
algorithm if the force coupling constant has been set by default.

[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 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:]
2013-11-08 04:25:37 +08:00
This fix is part of the USER-LB package. It is only enabled if LAMMPS
was built with that package. See the "Making
LAMMPS"_Section_start.html#start_3 section for more info.
2013-11-08 04:17:04 +08:00
2013-11-08 04:25:37 +08:00
Can only be used if a lattice-Boltzmann fluid has been created via the
"fix lb/fluid"_fix_lb_fluid.html command, and must come after this
command.
