fix lb/pc command :h3
|
||
|
|
|
||
|
|
[Syntax:]
|
||
|
|
|
||
|
|
fix ID group-ID lb/pc :pre
|
||
|
|
|
||
|
|
ID, group-ID are documented in the "fix"_fix.html command :ulb,l
|
||
|
|
lb/pc = style name of this fix command :l
|
||
|
|
:ule
|
||
|
|
|
||
|
|
[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 [1]. 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:]
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
This fix can only be used if LAMMPS was built with the
|
||
|
|
"fluid" package. See the "Making
|
||
|
|
LAMMPS"_Section_start.html#2_3 section for more info on packages.
