/* 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 freeze requires atom attribute torque

The atom style defined does not have this attribute.

E: More than one fix freeze

Only one of these fixes can be defined, since the granular pair
potentials access it.
