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