fix nve/tri command :h3
|
|
|
|
[Syntax:]
|
|
|
|
fix ID group-ID nve/tri :pre
|
|
|
|
ID, group-ID are documented in "fix"_fix.html command
|
|
nve/tri = style name of this fix command :ul
|
|
|
|
[Examples:]
|
|
|
|
fix 1 all nve/tri :pre
|
|
|
|
[Description:]
|
|
|
|
Perform constant NVE integration to update position, velocity,
|
|
orientation, and angular momentum for triangular particles in the
|
|
group each timestep. V is volume; E is energy. This creates a system
|
|
trajectory consistent with the microcanonical ensemble. See the
|
|
"Howto spherical"_Howto_spherical.html doc page for an overview of
|
|
using triangular 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"_Howto_output.html.
|
|
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 ASPHERE package. It is only enabled if LAMMPS
|
|
was built with that package. See the "Build
|
|
package"_Build_package.html doc page for more info.
|
|
|
|
This fix requires that particles be triangles as defined by the
|
|
"atom_style tri"_atom_style.html command.
