<h2>Description</h2>
<p>Using a pair style of none means pair forces and energies 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"><span class="doc">neighbor</span></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"><span class="doc">neighbor</span></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>
<p>See the <a class="reference internal" href="pair_zero.html"><span class="doc">pair_style zero</span></a> for a way to trigger the
building of a neighbor lists, but compute no pairwise interactions.</p>
