Summary: We present a Lagrangian numerical method valid in any space dimension for approximating solutions to the incompressible Euler equation. The method is based on the canonical Hamiltonian formulation of incompressible flow. The method preserves at least three invariants of the flow: the kinetic energy, the impulse, and the angular momentum. We present numerical results which validate the method and elucidate the structure of the Hamiltonian variables in two and three dimensions.
