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
|
|
|
|

|
|
|
|
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.
