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"_run_style.html is {respa}, dt is the timestep for
|
|
the outer loop (largest) timestep.
|
|
|
|
[Restrictions:] none
|
|
|
