+
+Description
+"""""""""""
+
+Using a pair style of none means pair forces and energies are not
+computed.
+
+With this choice, the force cutoff is 0.0, which means that only atoms
+within the neighbor skin distance (see the :doc:`neighbor <neighbor>`
+command) are communicated between processors.  You must insure the
+skin distance is large enough to acquire atoms needed for computing
+bonds, angles, etc.
+
+A pair style of *none* will also prevent pairwise neighbor lists from
+being built.  However if the :doc:`neighbor <neighbor>` style is *bin*\ ,
+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
+*nsq* or set the skin distance to a larger value.
+
+See the :doc:`pair_style zero <pair_zero>` for a way to trigger the
+building of a neighbor lists, but compute no pairwise interactions.
