/* ERROR/WARNING messages:
E: Illegal ... command
Self-explanatory. Check the input script syntax and compare to the
documentation for the command. You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.
E: Pair style hybrid cannot have hybrid as an argument
Self-explanatory.
E: Pair style hybrid cannot have none as an argument
Self-explanatory.
E: Incorrect args for pair coefficients
Self-explanatory. Check the input script or data file.
E: Pair coeff for hybrid has invalid style
Style in pair coeff must have been listed in pair_style command.
E: Pair hybrid sub-style is not used
No pair_coeff command used a sub-style specified in the pair_style
command.
E: All pair coeffs are not set
All pair coefficients must be set in the data file or by the
pair_coeff command before running a simulation.
E: Invoked pair single on pair style none
A command (e.g. a dump) attempted to invoke the single() function on a
pair style none, which is illegal. You are probably attempting to
compute per-atom quantities with an undefined pair style.
E: Pair hybrid sub-style does not support single call
You are attempting to invoke a single() call on a pair style
that doesn't support it.
E: Coulomb cutoffs of pair hybrid sub-styles do not match
If using a Kspace solver, all Coulomb cutoffs of long pair styles must
be the same.
