/* ERROR/WARNING messages:

E: Internal error in atom_style body

This error should not occur.  Contact the developers.

E: Invalid atom_style body command

No body style argument was provided.

E: Unrecognized body style

The choice of body style is unknown.

E: Per-processor system is too big

The number of owned atoms plus ghost atoms on a single
processor must fit in 32-bit integer.

E: Invalid atom type in Atoms section of data file

Atom types must range from 1 to specified # of types.

E: Invalid density in Atoms section of data file

Density value cannot be <= 0.0.

E: Assigning body parameters to non-body atom

Self-explanatory.

E: Assigning quat to non-body atom

Self-explanatory.
