Second-order bulk-surface splitting for the wave equation with kinetic boundary conditions
R. Altmann, R. Morandin
This paper is devoted to the numerical analysis of a second-order bulk--surface splitting scheme for the semi-linear wave equation with kinetic boundary conditions. The constructio…

Discrete gradient methods for port-Hamiltonian differential-algebraic equations
Philipp L. Kinon, Riccardo Morandin, Philipp Schulze
Discrete gradient methods are a powerful tool for the time discretization of dynamical systems, since they are structure-preserving regardless of the form of the total energy. In t…
