/* 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: Fix wall/piston command only available at zlo

The face keyword must be zlo.

E: Must shrink-wrap piston boundary

The boundary style of the face where the piston is applied must be of
type s (shrink-wrapped).

E: Illegal fix wall/piston velocity

The piston velocity must be positive.

E: Cannot use wall in periodic dimension

Self-explanatory.

E: NL ramp in wall/piston only implemented in zlo for now

The ramp keyword can only be used for piston applied to face zlo.
