fix lb/pc command :h3
|
|
|
|
[Syntax:]
|
|
|
|
fix ID group-ID lb/pc :pre
|
|
|
|
ID, group-ID are documented in the "fix"_fix.html command
|
|
lb/pc = style name of this fix command :ul
|
|
|
|
[Examples:]
|
|
|
|
fix 1 all lb/pc :pre
|
|
|
|
[Description:]
|
|
|
|
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:]
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|

|
|

|
|
|
|
[Default:] None.
