Towards Real-Time Magnetic Dosimetry Simulations for Inductive Charging Systems
Norman Haussmann, Martin Zang, Robin Mease +3
The exposure of a human by magneto-quasistatic fields from wireless charging systems is to be determined from magnetic field measurements in near real-time. This requires a fast li…
Krylov Subspace Recycling for Evolving Structures
Matthias Bolten, Eric de Sturler, Camilla Hahn
Krylov subspace recycling is a powerful tool for solving long series of large, sparse linear systems that change slowly. In PDE constrained shape optimization, these appear natural…
Toeplitz Momentary Symbols: definition, results, and limitations in the spectral analysis of Structured Matrices
Matthias Bolten, Sven-Erik Ekström, Isabella Furci +1
A powerful tool for analyzing and approximating the singular values and eigenvalues of structured matrices is the theory of GLT sequences. By the GLT theory one can derive a functi…
Event-based update of synapses in voltage-based learning rules
Jonas Stapmanns, Jan Hahne, Moritz Helias +3
Due to the point-like nature of neuronal spiking, efficient neural network simulators often employ event-based simulation schemes for synapses. Yet many types of synaptic plasticit…
Non-overlapping block smoothers for the Stokes equations
Lisa Claus, Matthias Bolten
Overlapping block smoothers efficiently damp the error contributions from highly oscillatory components within multigrid methods for the Stokes equations but they are computational…
PyMGRIT: A Python Package for the parallel-in-time method MGRIT
Jens Hahne, Stephanie Friedhoff, Matthias Bolten
In this paper, we introduce the Python framework PyMGRIT, which implements the multigrid-reduction-in-time (MGRIT) algorithm for solving the (non-)linear systems arising from the d…
Tracing locally Pareto optimal points by numerical integration
Matthias Bolten, Onur Tanil Doganay, Hanno Gottschalk +1
We suggest a novel approach for the efficient and reliable approximation of the Pareto front of sufficiently smooth unconstrained bi-criteria optimization problems. Optimality cond…
GivEn -- Shape Optimization for Gas Turbines in Volatile Energy Networks
Jan Backhaus, Matthias Bolten, Onur Tanil Doganay +19
This paper describes the project GivEn that develops a novel multicriteria optimization process for gas turbine blades and vanes using modern "adjoint" shape optimization algorithm…
