exchangeForces send force contributions from each process on which a particle exists to the particle owner. The total hydrodynamic force is then computed by the particle owner as the sum of all the force contributions (which physically are the surface forces from the part of the particle surface handled by each process). The owner then updates particle velocity in a subsequent call to a different routine. For momentum-exchange method only!
