<h2>Description<a class="headerlink" href="#description" title="Permalink to this headline"></a></h2>
<p>Using a pair style of none means pair forces are not computed.</p>
<p>With this choice, the force cutoff is 0.0, which means that only atoms
within the neighbor skin distance (see the <a class="reference internal" href="neighbor.html"><em>neighbor</em></a>
command) are communicated between processors. You must insure the
skin distance is large enough to acquire atoms needed for computing
bonds, angles, etc.</p>
<p>A pair style of <em>none</em> will also prevent pairwise neighbor lists from
being built. However if the <a class="reference internal" href="neighbor.html"><em>neighbor</em></a> style is <em>bin</em>,
data structures for binning are still allocated. If the neighbor skin
distance is small, then these data structures can consume a large
amount of memory. So you should either set the neighbor style to
<em>nsq</em> or set the skin distance to a larger value.</p>
