pair_style zero command
+
+
Syntax
+
+
+zero = style name of this pair style
+cutoff = global cutoff (distance units)
+
+
+
+
Examples
+
pair_style zero
+pair_coeff * *
+pair_coeff 1 2 3.0
+
+
+
+
+
Description
+
Define a global cutoff length for the purpose of building a neighbor
+list and acquiring ghost atoms, but do not compute any pairwise
+forces.
+
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 fix bond/create compute rdf compute voronoi/atom
+
Note that the comm_modify cutoff
+
The following coefficients must be defined for each pair of atoms
+types via the pair_coeff read_data read_restart
+
+cutoff (distance units)
+
+
This coefficient is optional. If not specified, the global cutoff
+specified in the pair_style command is used.
