In the preceding paper, momentum equations of a Hamiltonian particle method are derived from direct discretization of the Lagrangian for inviscid incompressible fluid flows. They are a Hamiltonian system with holonomic constraints. In this paper, the RATTLE algorithm which is a symplectic scheme for constrained Hamiltonian systems is adopted to improve the quality of the particle method. Then traveling surface waves are simulated to examine the Hamiltonian particle method. The result shows the superior mechanical energy conservation property of the method.
