[lammps-users] why timestep for ReaxFF should be very small?

Dear All,

I want to make sure whether timestep for ReaxFF should be around 0.02 instead of 1 fs as other potential. Is it true?
Is there one could explain the reason clearly?

best regards,

If you look at the 2 examples in examples/reax,
neither of them use that small of timestep.
