Symplectic multirate generalized additive Runge-Kutta methods for Hamiltonian systems
Kevin Schäfers, Michael Günther, Adrian Sandu
The generalized additive Runge-Kutta (GARK) framework provides a powerful approach for solving additively partitioned ordinary differential equations. This work combines the ideas…
