<h2>Description<aclass="headerlink"href="#description"title="Permalink to this headline">¶</a></h2>
<p>Define a global cutoff length for the purpose of building a neighbor
list and acquiring ghost atoms, but do not compute any pairwise forces
or energies.</p>
<p>This can be useful for fixes or computes which require a neighbor list
to enumerate pairs of atoms within some cutoff distance, but when
pairwise forces are not otherwise needed. Examples are the <aclass="reference internal"href="fix_bond_create.html"><em>fix bond/create</em></a>, <aclass="reference internal"href="compute_rdf.html"><em>compute rdf</em></a>,
<p>Note that the <aclass="reference internal"href="comm_modify.html"><em>comm_modify cutoff</em></a> command can be
used to insure communication of ghost atoms even when a pair style is
not defined, but it will not trigger neighbor list generation.</p>
<p>The following coefficients must be defined for each pair of atoms
types via the <aclass="reference internal"href="pair_coeff.html"><em>pair_coeff</em></a> command as in the examples
above, or in the data file or restart files read by the
<aclass="reference internal"href="read_data.html"><em>read_data</em></a> or <aclass="reference internal"href="read_restart.html"><em>read_restart</em></a>
commands, or by mixing as described below:</p>
<ulclass="simple">
<li>cutoff (distance units)</li>
</ul>
<p>This coefficient is optional. If not specified, the global cutoff
<p>The cutoff distance for this pair style can be mixed. The default mix
value is <em>geometric</em>. See the “pair_modify” command for details.</p>
<p>This pair style does not support the <aclass="reference internal"href="pair_modify.html"><em>pair_modify</em></a>
shift, table, and tail options.</p>
<p>This pair style writes its information to <aclass="reference internal"href="restart.html"><em>binary restart files</em></a>, so pair_style and pair_coeff commands do not need
to be specified in an input script that reads a restart file.</p>
<p>This pair style can only be used via the <em>pair</em> keyword of the
<aclass="reference internal"href="run_style.html"><em>run_style respa</em></a> command. It does not support the
