/* 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: Wall defined twice in fix wall/reflect command

Self-explanatory.

E: Cannot use fix wall/reflect in periodic dimension

Self-explanatory.

E: Cannot use fix wall/reflect zlo/zhi for a 2d simulation

Self-explanatory.

E: Use of fix wall with undefined lattice

Must use lattice command with fix wall command if units option is set
to lattice.

E: Variable name for fix wall/reflect does not exist

Self-explanatory.

E: Variable for fix wall/reflect is invalid style

Only equal-style variables can be used.

W: Should not allow rigid bodies to bounce off relecting walls

LAMMPS allows this, but their dynamics are not computed correctly.
