/* 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 heat does not exist

Self-explanatory.

E: Variable name for fix heat does not exist

Self-explanatory.

E: Variable for fix heat is invalid style

Only equal-style or atom-style variables can be used.

E: Fix heat group has no atoms

Self-explanatory.

E: Fix heat kinetic energy went negative

This will cause the velocity rescaling about to be performed by fix
heat to be invalid.

E: Fix heat kinetic energy of an atom went negative

This will cause the velocity rescaling about to be performed by fix
heat to be invalid.
