/* 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: Compute group/group group ID does not exist
Self-explanatory.
E: Compute group/group molecule requires molecule IDs
UNDOCUMENTED
E: No pair style defined for compute group/group
Cannot calculate group interactions without a pair style defined.
E: Pair style does not support compute group/group
The pair_style does not have a single() function, so it cannot be
invoked by the compute group/group command.
E: No Kspace style defined for compute group/group
Self-explanatory.
E: Kspace style does not support compute group/group
Self-explanatory.
W: Both groups in compute group/group have a net charge; the Kspace boundary correction to energy will be non-zero
Self-explanatory.
