/* 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 hexorder/atom requires a pair style be defined
|
|
|
|
Self-explanatory.
|
|
|
|
E: Compute hexorder/atom cutoff is longer than pairwise cutoff
|
|
|
|
Cannot compute order parameter beyond cutoff.
|
|
|
|
W: More than one compute hexorder/atom
|
|
|
|
It is not efficient to use compute hexorder/atom more than once.
