/* 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 region INF or EDGE when box does not exist
Regions that extend to the box boundaries can only be used after the
create_box command has been used.
E: Variable evaluation in region gave bad value
Variable returned a radius < 0.0.
E: Variable name for region cylinder does not exist
Self-explanatory.
E: Variable for region cylinder is invalid style
Only equal-style varaibles are allowed.
