Syntax:
pair_style morse cutoff
Examples:
pair_style morse 2.5 pair_coeff * * 100.0 2.0 1.5 pair_coeff 1 1 100.0 2.0 1.5 3.0
Description:
Style morse 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 command as in the examples above, or in the data file or restart files read by the read_data or read_restart commands:
The last coefficient is optional. If not specified, the global morse cutoff is used.
Restrictions:
The morse potential does not support the pair_modify mix option. Coefficients for all i,j pairs must be specified explicitly.
