fix meso/stationary command :h3
|
|
|
|
[Syntax:]
|
|
|
|
fix ID group-ID meso/stationary :pre
|
|
|
|
ID, group-ID are documented in "fix"_fix.html command
|
|
meso = style name of this fix command :ul
|
|
|
|
[Examples:]
|
|
|
|
fix 1 boundary meso/stationary :pre
|
|
|
|
[Description:]
|
|
|
|
Perform time integration to update internal energy and local density,
|
|
but not position or velocity for atoms in the group each timestep.
|
|
This fix is needed for SPH simulations to correctly time-integrate
|
|
fixed boundary particles which constrain a fluid to a given region in
|
|
space.
|
|
|
|
See "this PDF guide"_USER/sph/SPH_LAMMPS_userguide.pdf to using SPH in
|
|
LAMMPS.

[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#howto_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-SPH 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.
