velocity zero linear command?

Is the velocity zero linear command doing what I think it should? I am trying to hold the COM velocity of a group to zero. I have tried the “velocity zero linear” command but the group still appears to drift around. Does the command zero the linear momentum at every time step or just initialize the COM to zero at the beginning of the run?

Thanks,

Dave

The velocity command is a one-time action. You would need
a fix, like fix momentum or fix recenter to act continuually
during a run.
