pair_style dipole/cut command :h3
[Syntax:]
pair_style dipole/cut cutoff (cutoff2) :pre
cutoff = global cutoff for LJ interactions (and Coulombic if only 1 arg) (distance units)
cutoff2 = global cutoff for Coulombic and dipole interactions (optional) (distance units) :ul
[Examples:]
pair_style dipole/cut 2.5
pair_style dipole/cut 2.5 5.0
pair_coeff * * 100.0 2.0 1.5
pair_coeff 1 1 100.0 2.0 1.5 3.0 :pre
[Description:]
Style {dipole/cut}
The {dipole} styles are not yet implemented in LAMMPS. They will
enable a point dipole and charge to be assigned to each atom and the
resulting charge-dipole and dipole-dipole interactions to be computed.
computes pairwise interactions with the formula
:c,image(Eqs/pair_dipole.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:
D0 (energy units)
alpha (1/distance units)
r0 (distance units)
cutoff (distance units) :ul
The last coefficient is optional. If not specified, the global morse
cutoff is used.
[Restrictions:] none
Must use atom style dipole.
