### fix nve/gran command

Syntax:

    fix ID group-ID nve/gran

- ID, group-ID are documented in fix command
- nve/gran = style name of this fix command

Examples:

    fix 1 all nve/gran

Description:

Perform constant NVE updates each timestep on a group of atoms of atom style granular. V is volume; E is energy. Granular atoms store rotational information as well as position and velocity, so this integrator updates translational and rotational degrees of freedom due to forces and torques.

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 scalar or vector 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: none

This fix is part of the "granular" package. It is only enabled if LAMMPS was built with that package. See the Making LAMMPS section for more info.
