Syntax:
dihedral_style quadratic
Examples:
dihedral_style quadratic dihedral_coeff 100.0 80.0
Description:
The quadratic dihedral style uses the potential:
This dihedral potential can be used to keep a dihedral in a predefined value.
The following coefficients must be defined for each dihedral type via the dihedral_coeff command as in the example above, or in the data file or restart files read by the read_data or read_restart commands:
K (energy) phi0 (degrees)
Restrictions:
This angle style can only be used if LAMMPS was built with the USER_MISC package. See the Making LAMMPS section for more info on packages.
