Model order reduction via Lie groups
Yannik P. Wotte, Patrick Buchfink, Silke Glas +2
Lie groups and their actions are ubiquitous in the description of physical systems, and we explore implications in the setting of model order reduction (MOR). We present a novel fr…
Fast prediction of plasma instabilities with sparse-grid-accelerated optimized dynamic mode decomposition
Kevin Gill, Ionut-Gabriel Farcas, Silke Glas +1
Parametric data-driven reduced-order models (ROMs) that embed dependencies in a large number of input parameters are crucial for enabling many-query tasks in large-scale problems.…
Energy-stable Port-Hamiltonian Systems
Patrick Buchfink, Silke Glas, Hans Zwart
We combine energy-stable and port-Hamiltonian (pH) systems to obtain energy-stable port-Hamiltonian (espH) systems. The idea is to extend the known energy-stable systems with an in…
Leveraging time and parameters for nonlinear model reduction methods
Silke Glas, Benjamin Unger
In this paper, we consider model order reduction (MOR) methods for problems with slowly decaying Kolmogorov -widths as, e.g., certain wave-like or transport-dominated problems.…
