/* 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: Region ID for fix wall/region does not exist
Self-explanatory.
E: Fix wall/region cutoff <= 0.0
Self-explanatory.
E: Fix wall/region colloid requires atom style sphere
Self-explanatory.
E: Fix wall/region colloid requires extended particles
One of the particles has radius 0.0.
E: Particle outside surface of region used in fix wall/region
Particles must be inside the region for energy/force to be calculated.
A particle outside the region generates an error.
