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: Improper style hybrid cannot use same improper style twice
Self-explanatory.
E: Improper style hybrid cannot have hybrid as an argument
Self-explanatory.
E: Improper style hybrid cannot have none as an argument
Self-explanatory.
E: Improper coeff for hybrid has invalid style
Improper style hybrid uses another improper style as one of its
coefficients. The improper style used in the improper_coeff command
or read from a restart file is not recognized.
