correct_velocity

This keyword allows one to enforce zero angular momentum. This can be useful as the stochastic nature of most thermostats and barostats available in gpumd can cause the conservation of angular momentum to be violated.

Syntax

• This keyword only has one parameter, which is the interval between which the angular momentum is set to zero:

  correct_velocity <interval>
  

Example

The command:

correct_velocity 10

implies that the angular momentum is strictly set to zero every 10 steps.
