### reset_timestep command

Syntax:

    reset_timestep N

- N = timestep number

Examples:

    reset_timestep 0
    reset_timestep 4000000

Description:

Set the timestep counter to the specified value. This command normally comes after the timestep has been set by reading it in from a file or a previous simulation advanced the timestep.

The read_data and create_box commands set the timestep to 0; the read_restart command sets the timestep to the value it had when the restart file was written.

Restrictions: none

This command cannot be used when a dump file is defined via the dump command and has already been written to. It also cannot be used when a restart frequency has been set, and a restart file has already been written. This is because the changed timestep can mess up the planned timestep for the next file write. See the undump command or restart 0 command for info on how to turn off these definitions if necessary. New specifications for dump and restart files can be given after the reset_timestep command is used.

This command cannot be used when any fixes are defined that keep track of time or the timestep in order to perform time-dependent operations. Examples include the "ave" or "wall" fixes such as fix ave/spatial or fix wall/lj126, and also fix indent. The wall and indeter fixes allow for a velocity or other time-dependent parameter to be specified, which would be messed up by resetting the timestep.

Restting the timestep will clear the flags for computes that may have calculated some quantity from a previous run. This means that quantity cannot be accessed by a variable in between runs until a new run is performed. See the variable command for more details.
