Syntax:
bond_style nonlinear
Examples:
bond_style nonlinear bond_coeff 2 100.0 1.1 1.4
Description:
The nonlinear bond style uses the potential
to define an anharmonic spring (Rector) of equilibrium length r0 and maximum extension lamda.
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 MOLECULAR package (which it is by default). See the Making LAMMPS section for more info on packages.

Default: none
