angle_style zero command :h3
|
|
|
|
[Syntax:]
|
|
|
|
angle_style zero {nocoeff} :pre
|
|
|
|
[Examples:]
|
|
|
|
angle_style zero
|
|
angle_style zero nocoeff
|
|
angle_coeff *
|
|
angle_coeff * 120.0 :pre
|
|
|
|
[Description:]
|
|
|
|
Using an angle style of zero means angle forces and energies are not
|
|
computed, but the geometry of angle triplets is still accessible to
|
|
other commands.
|
|
|
|
As an example, the "compute angle/local"_compute_angle_local.html
|
|
command can be used to compute the theta values for the list of
|
|
triplets of angle atoms listed in the data file read by the
|
|
"read_data"_read_data.html command. If no angle style is defined,
|
|
this command cannot be used.
|
|
|
|
The optional {nocoeff} flag allows to read data files with AngleCoeff
|
|
section for any angle style. Similarly, any angle_coeff commands
|
|
will only be checked for the angle type number and the rest ignored.
|
|
|
|
Note that the "angle_coeff"_angle_coeff.html command must be used for
|
|
all angle types. If specified, there can be only one value, which is
|
|
going to be used to assign an equilibrium angle, e.g. for use with
|
|
"fix shake"_fix_shake.html.
