timestep command¶
Examples¶
timestep 2.0
timestep 0.003
Description¶
Set the timestep size for subsequent molecular dynamics simulations. See the units command for a discussion of time units. The default value for the timestep also depends on the choice of units for the simulation; see the default values below.
When the run style is respa, dt is the timestep for the outer loop (largest) timestep.
Restrictions¶
none
Default¶
timestep = 0.005 tau for units = lj
timestep = 1.0 fmsec for units = real
timestep = 0.001 psec for units = metal
timestep = 1.0e-8 sec (10 nsec) for units = si or cgs
