/* 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: Angle style hybrid cannot use same angle style twice
Self-explanatory.
E: Angle style hybrid cannot have hybrid as an argument
Self-explanatory.
E: Angle style hybrid cannot have none as an argument
Self-explanatory.
E: Angle coeff for hybrid has invalid style
Angle style hybrid uses another angle style as one of its
coefficients. The angle style used in the angle_coeff command or read
from a restart file is not recognized.
E: Invoked angle equil angle on angle style none
Self-explanatory.
E: Invoked angle single on angle style none
Self-explanatory.
