We discuss algorithms applicable to the numerical solution of second-order
ordinary differential equations by finite-differences. We make particular
reference to the solution of the dissipative particle dynamics fluid model, and
present extensive results comparing one of the algorithms discussed with the
standard method of solution. These results show the successful modeling of
phase separation and surface tension in a binary immiscible fluid mixture.Comment: 27 pages RevTeX, 9 figures, J. Chem. Phys. (in press
