### fix reax/bonds command

Syntax:

    fix ID group-ID reax/bonds Nevery filename

- ID, group-ID are documented in fix command
- reax/bonds = style name of this fix command
- Nevery = output interval in timesteps
- filename = name of output file

Examples:

fix 1 all reax/bonds 100 bonds.tatb

Description:

Write out the bond information computed by the ReaxFF potential specified by pair_style reax. The bond information is written to filename on timesteps that are multiples of Nevery, including timestep 0.

The format of the output file should be self-explantory.

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:

This fix requires that the pair_style reax be invoked. This fix is part of the "reax" package. It is only enabled if LAMMPS was built with that package, which also requires the REAX library be built and linked with LAMMPS. See the Making LAMMPS section for more info.
