13 fix ID group-ID lb/pc :pre
15 ID, group-ID are documented in the "fix"_fix.html command
16 lb/pc = style name of this fix command :ul
24 Update the positions and velocities of the individual particles
25 described by {group-ID}, experiencing velocity-dependent hydrodynamic
26 forces, using the integration algorithm described in "Mackay et
27 al."_#Mackay. This integration algorithm should only be used if a
28 user-specified value for the force-coupling constant used in "fix
29 lb/fluid"_fix_lb_fluid.html has been set; do not use this integration
30 algorithm if the force coupling constant has been set by default.
32 [Restart, fix_modify, output, run start/stop, minimize info:]
34 No information about this fix is written to "binary restart
35 files"_restart.html. None of the "fix_modify"_fix_modify.html options
36 are relevant to this fix. No global or per-atom quantities are stored
37 by this fix for access by various "output
38 commands"_Section_howto.html#howto_15. No parameter of this fix can be
39 used with the {start/stop} keywords of the "run"_run.html command.
40 This fix is not invoked during "energy minimization"_minimize.html.
44 This fix is part of the USER-LB package. It is only enabled if LAMMPS
45 was built with that package. See the "Making
46 LAMMPS"_Section_start.html#start_3 section for more info.
48 Can only be used if a lattice-Boltzmann fluid has been created via the
49 "fix lb/fluid"_fix_lb_fluid.html command, and must come after this
54 "fix lb/fluid"_fix_lb_fluid.html "fix
55 lb/rigid/pc/sphere"_fix_lb_rigid_pc_sphere.html
