Modeling of radiating curved cables via coupled telegrapher's and Maxwell's equations
Markus Clemens, Michael Günther, Timo Reis +1
We investigate the electromagnetic interactions of cable harnesses in the time domain. We present a novel model that allows for curved cables, extending the standard assumptions ty…
Hessian-free force-gradient integrators and their application to lattice QCD simulations
Kevin Schäfers, Jacob Finkenrath, Michael Günther +1
We present initial results on Hessian-free force-gradient integrators for lattice field theories. Integrators of this framework promise to provide substantial performance enhanceme…
Operator splitting for semi-explicit differential-algebraic equations and port-Hamiltonian DAEs
Andreas Bartel, Malak Diab, Andreas Frommer +1
Operator splitting methods allow to split the operator describing a complex dynamical system into a sequence of simpler subsystems and treat each part independently. In the modelin…
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…
Enhanced fifth order WENO Shock-Capturing Schemes with Deep Learning
Tatiana Kossaczká, Matthias Ehrhardt, Michael Günther
In this paper we enhance the well-known fifth order WENO shock-capturing scheme by using deep learning techniques. This fine-tuning of an existing algorithm is implemented by train…
Higher Strong Order Methods for Itô SDEs on Matrix Lie Groups
Michelle Muniz, Matthias Ehrhardt, Michael Günther +1
In this paper we present a general procedure for designing higher strong order methods for Itô stochastic differential equations on matrix Lie groups and illustrate this strategy w…
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…
Variance-based Robust Optimization of a Permanent Magnet Synchronous Machine
Piotr A. Putek, E. Jan. W. ter Maten, Michael Günther +1
This paper focuses on the application of the variance-based global sensitivity analysis for a topology derivative method in order to solve a stochastic nonlinear time-dependent mag…
