@ -80,10 +80,12 @@ For a given entry, if the first three arguments are all different,
then the entry is for the {K} and {theta_0} parameters (the cutoff in
this case is irrelevant).
It is {not} required that the potential file contain entries for all
of the elements listed in the pair_coeff command. It can also contain
entries for additional elements not being used in a particular
simulation; LAMMPS ignores those entries.
It is required that the potential file contains entries for {all}
permutations of the elements listed in the pair_coeff command.
If certain combinations are not parameterized the corresponding
parameters should be set to zero. The potential file can also
contain entries for additional elements which are not used in
a particular simulation; LAMMPS ignores those entries.
