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#start_3 section for more info on packages.
[Related commands:]
"angle_coeff"_angle_coeff.html
[Default:] none
