9 pair_style none command :h3
21 Using a pair style of none means pair forces and energies are not
24 With this choice, the force cutoff is 0.0, which means that only atoms
25 within the neighbor skin distance (see the "neighbor"_neighbor.html
26 command) are communicated between processors. You must insure the
27 skin distance is large enough to acquire atoms needed for computing
30 A pair style of {none} will also prevent pairwise neighbor lists from
31 being built. However if the "neighbor"_neighbor.html style is {bin},
32 data structures for binning are still allocated. If the neighbor skin
33 distance is small, then these data structures can consume a large
34 amount of memory. So you should either set the neighbor style to
35 {nsq} or set the skin distance to a larger value.
37 See the "pair_style zero"_pair_zero.html for a way to trigger the
38 building of a neighbor lists, but compute no pairwise interactions.
