fix nve/body command :h3
|
|
|
|
[Syntax:]
|
|
|
|
fix ID group-ID nve/body :pre
|
|
|
|
ID, group-ID are documented in "fix"_fix.html command
|
|
nve/body = style name of this fix command :ul
|
|
|
|
[Examples:]
|
|
|
|
fix 1 all nve/body :pre
|
|
|
|
[Description:]
|
|
|
|
Perform constant NVE integration to update position, velocity,
|
|
orientation, and angular velocity for body particles in the group each
|
|
timestep. V is volume; E is energy. This creates a system trajectory
|
|
consistent with the microcanonical ensemble. See "Section_howto
|
|
14"_Section_howto.html#howto_14 of the manual and the "body"_body.html
|
|
doc page for more details on using body particles.
|
|
|
|
This fix differs from the "fix nve"_fix_nve.html command, which
|
|
assumes point particles and only updates their position and velocity.
|
|
|
|
[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 BODY 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.
|
|
|
|
This fix requires that atoms store torque and angular momementum and a
|
|
quaternion as defined by the "atom_style body"_atom_style.html
|
|
command.
|
|
|
|
All particles in the group must be body particles. They cannot be
|
|
point particles.
