You could make the vector<Vector3r>
LeapFrogPositionIntegrator::prevVelocities public, then you could change
it from anywhere: reset prevVelocities for particles in question and set
velocity of the particle itself to zero as well.

How and where do you load these particles? If you load/save simulation,
prevVelocities will be empty and the problem doesn't arise.
