/* 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: Cannot use dynamic group with fix adapt atom

This is not yet supported.

E: Variable name for fix adapt does not exist

Self-explanatory.

E: Variable for fix adapt is invalid style

Only equal-style variables can be used.

E: Fix adapt pair style does not exist

Self-explanatory

E: Fix adapt pair style param not supported

The pair style does not know about the parameter you specified.

E: Fix adapt pair style param is not compatible

Self-explanatory

E: Fix adapt type pair range is not valid for pair hybrid sub-style

Self-explanatory.

E: Fix adapt bond style does not exist

UNDOCUMENTED

E: Fix adapt bond style param not supported

UNDOCUMENTED

E: Fix adapt does not support bond_style hybrid

UNDOCUMENTED

E: Fix adapt kspace style does not exist

Self-explanatory.

E: Fix adapt requires atom attribute diameter

The atom style being used does not specify an atom diameter.

E: Fix adapt requires atom attribute charge

The atom style being used does not specify an atom charge.

E: Could not find fix adapt storage fix ID

This should not happen unless you explicitly deleted
a secondary fix that fix adapt created internally.
