fix nve/line command :h3

[Syntax:]

fix ID group-ID nve/line :pre

ID, group-ID are documented in "fix"_fix.html command
nve/line = style name of this fix command :ul

[Examples:]

fix 1 all nve/line :pre

[Description:]

Perform constant NVE integration to update position, velocity,
orientation, and angular velocity for line segment 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 of the manual for an overview of
using line segment 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_8.  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 requires that particles be line segments as defined by the
"atom_style line"_atom_style.html command.

[Related commands:]

"fix nve"_fix_nve.html, "fix nve/asphere"_fix_nve_asphere.html

[Default:] none
