dihedral_style multi/harmonic command :h3
|
|
|
|
[Syntax:]
|
|
|
|
dihedral_style multi/harmonic :pre
|
|
|
|
[Examples:]
|
|
|
|
dihedral_style multi/harmonic
|
|
dihedral_coeff 1 20 20 20 20 20 :pre
|
|
|
|
[Description:]
|
|
|
|
The {multi/harmonic} dihedral style uses the potential
|
|
|
|
:c,image(Eqs/dihedral_multi_harmonic.jpg)
|
|
|
|
The following coefficients must be defined for each dihedral type via the
|
|
"dihedral_coeff"_dihedral_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:
|
|
|
|
A1 (energy)
|
|
A2 (energy)
|
|
A3 (energy)
|
|
A4 (energy)
|
|
A5 (energy) :ul
|
|
|
|
[Restrictions:]
|
|
|
|
Dihedral styles can only be set for atom styles that allow dihedrals to be
|
|
defined.
|
|
|
|
This dihedral style is part of the "molecular" package. It is only
|
|
enabled if LAMMPS was built with that package. See the "Making
|
|
LAMMPS"_Section_start.html#2_2 section for more info.
