:line

angle_style cosine command :h3

[Syntax:]

angle_style cosine :pre

[Examples:]

angle_style cosine
angle_coeff * 75.0 :pre

[Description:]

The {cosine} angle style uses the potential

:c,image(Eqs/angle_cosine.jpg)

where K is defined for each angle type.

The following coefficients must be defined for each angle type via the
"angle_coeff"_angle_coeff.html command as in the example above, or in
the data file or restart files read by the "read_data"_read_data.html
or "read_restart"_read_restart.html commands:

K (energy) :ul

[Restrictions:]

This angle style can only be used if LAMMPS was built with the
"molecular" package (which it is by default).  See the "Making
LAMMPS"_Section_start.html#2_3 section for more info on packages.

[Related commands:]

"angle_coeff"_angle_coeff.html

[Default:] none
