  /* 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.
