9 bond_style zero command :h3
13 bond_style zero {nocoeff} :pre
18 bond_style zero nocoeff
20 bond_coeff * 2.14 :pre
24 Using an bond style of zero means bond forces and energies are not
25 computed, but the geometry of bond pairs is still accessible to other
28 As an example, the "compute bond/local"_compute_bond_local.html
29 command can be used to compute distances for the list of pairs of bond
30 atoms listed in the data file read by the "read_data"_read_data.html
31 command. If no bond style is defined, this command cannot be used.
33 The optional {nocoeff} flag allows to read data files with a BondCoeff
34 section for any bond style. Similarly, any bond_coeff commands
35 will only be checked for the bond type number and the rest ignored.
37 Note that the "bond_coeff"_bond_coeff.html command must be used for
38 all bond types. If specified, there can be only one value, which is
39 going to be used to assign an equilibrium distance, e.g. for use with
40 "fix shake"_fix_shake.html.
