pair_style yukawa command :h3
[Syntax:]
pair_style yukawa kappa cutoff :pre
kappa = screening length (inverse distance units)
cutoff = global cutoff for Yukawa interactions (distance units) :ul
[Examples:]
pair_style yukawa 2.0 2.5
pair_coeff 1 1 100.0 2.3
pair_coeff * * 100.0 :pre
[Description:]
Style {yukawa} computes pairwise interactions with the formula
:c,image(Eqs/pair_yukawa.jpg)
Rc is the cutoff.
The following coefficients must be defined for each pair of atoms
types via the "pair_coeff"_pair_coeff.html command as in the examples
above, or in the data file or restart files read by the
"read_data"_read_data.html or "read_restart"_read_restart.html
commands:
A (energy units)
cutoff (distance units) :ul
The last coefficient is optional. If not specified, the global yukawa
cutoff is used.
[Restrictions:] none
[Related commands:]
"pair_coeff"_pair_coeff.html
[Default:] none
