|

<P>Write out the bond information computed by the ReaxFF potential

specified by <A HREF = "pair_reax.html">pair_style reax</A> or <A HREF = "pair_reax_c.html">pair_style
|
|
reax/c</A>. The bond information is written to

<I>filename</I> on timesteps that are multiples of <I>Nevery</I>, including
|
|
timestep 0.

<P>No information about this fix is written to <A HREF = "restart.html">binary restart
|
|
files</A>. None of the <A HREF = "fix_modify.html">fix_modify</A> options
|
|
are relevant to this fix. No global or per-atom quantities are stored
|
|
by this fix for access by various <A HREF = "Section_howto.html#howto_15">output
|
|
commands</A>. No parameter of this fix can
|
|
be used with the <I>start/stop</I> keywords of the <A HREF = "run.html">run</A> command.
|
|
This fix is not invoked during <A HREF = "minimize.html">energy minimization</A>.

<P><B>Restrictions:</B>
|
|
</P>
|
|
<P>The fix reax/bonds requires that the <A HREF = "pair_reax.html">pair_style reax</A>
|
|
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. The fix reax/c/bonds
|
|
requires that the <A HREF = "pair_reax_c.html">pair_style reax/c</A> be invoked,
|
|
which is part of the USER-REAXC package. It is only enabled if LAMMPS
|
|
was built with that package. See the <A HREF = "Section_start.html#start_3">Making
|
|
LAMMPS</A> section for more info.
