Syntax:
fix ID group-ID nve/line
Examples:
fix 1 all nve/line
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 of the manual for an overview of using line segment particles.
This fix differs from the fix nve 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. None of the fix_modify options are relevant to this fix. No global or per-atom quantities are stored by this fix for access by various output commands. No parameter of this fix can be used with the start/stop keywords of the run command. This fix is not invoked during energy minimization.
Restrictions:
This fix is part of the ASPHERE package. It is only enabled if LIGGGHTS(R)-PUBLIC was built with that package. See the Making LIGGGHTS(R)-PUBLIC section for more info.
This fix requires that particles be line segments as defined by the atom_style line command.
