Efficient implementation of geometric integrators for separable Hamiltonian problems
arXiv:1306.2439 · doi:10.1063/1.4825598
Abstract
We here investigate the efficient implementation of the energy-conserving methods named Hamiltonian Boundary Value Methods (HBVMs) recently introduced for the numerical solution of Hamiltonian problems. In this note, we describe an iterative procedure, based on a triangular splitting, for solving the generated discrete problems, when the problem at hand is separable.
