  The port-Hamiltonian approach presents an energy-based modeling of dynamical
systems with energy-conservative and energy-dissipative parts as well as an
interconnection over the so-called ports. In this paper, we apply an operator
splitting that treats the energy-conservative and energy-dissipative parts
separately. This paves the way for linear equation solvers to exploit the
respective special structures of the iteration matrices as well as the
multirate potential in the different right-hand sides. We illustrate the
approach using test examples from coupled multibody system dynamics.
