/* 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 nve/sphere requires atom style sphere

Self-explanatory.

E: Fix nve/sphere update dipole requires atom attribute mu

An atom style with this attribute is needed.

E: Fix nve/sphere requires extended particles

This fix can only be used for particles of a finite size.
 
E: Fix nve/sphere dlm must be used with update dipole
 
The DLM algorithm can only be used in conjunction with update dipole.
