correct_velocity

This keyword allows one to enforce zero linear and angular momenta at regular intervals.

Syntax

  • This keyword can have one or two parameters, which are the interval between which the linear and angular momenta are set to zero and an optional group method:

    correct_velocity <interval> [<group_method>]

  • interval must be larger than or equal to 10. A value between 10 and 100 should be good.

  • The group_method must be defined in model.xyz.

Example 1

The command:

correct_velocity 10

implies that the linear and angular momenta are set to zero every 10 steps.

Example 2

The command:

correct_velocity 50 3

implies that the linear and angular momenta for the individual groups in group method 3 are set to zero every 50 steps.
