Syntax:

bond_style class2 

Examples:

bond_style class2
bond_coeff 1 1.0 100.0 80.0 80.0 

Description:

The class2 bond style uses the potential

where r0 is the equilibrium bond distance.

See (Sun) for a description of the COMPASS class2 force field.

The following coefficients must be defined for each bond type via the bond_coeff command as in the example above, or in the data file or restart files read by the read_data or read_restart commands:

Restrictions:

This bond style can only be used if LAMMPS was built with the CLASS2 package. See the Making LAMMPS section for more info on packages.
