			timestep command :h3

			[Syntax:]

			timestep dt :pre

			dt = timestep size (time units) :ul

			[Examples:]

			timestep 2.0
			timestep 0.003 :pre

			[Description:]

			Set the timestep size for subsequent molecular dynamics simulations.
			See the "units"_units.html command for a discussion of time units.
			Note that using the units command also sets the timestep to its
			default value in the chosen units.

			When the run style is {respa}, dt is the timestep for the outer loop
			(largest) timestep.

			[Restrictions:] none

			[Related commands:]

			"run"_run.html, "run_style"_run_style.html respa, "units"_units.html

			[Default:]

			timestep = 0.005 tau for units = lj
			timestep = 1.0 fmsec for units = real
			timestep = 0.001 psec for units = metal :all(b)
