GPU Accelerated Explicit Time Integration Methods for Electro-Quasistatic Fields
Christian Richter, Sebastian Schöps, Markus Clemens
Electro-quasistatic field problems involving nonlinear materials are commonly discretized in space using finite elements. In this paper, it is proposed to solve the resulting syste…
Discretization of Maxwell's Equations for Non-inertial Observers Using Space-Time Algebra
Mariusz Klimek, Stefan Kurz, Sebastian Schoeps +1
We employ Maxwell's equations formulated in Space-Time Algebra to perform discretization of moving geometries directly in space-time. All the derivations are carried out without an…
Low-Dimensional Stochastic Modeling of the Electrical Properties of Biological Tissues
Ulrich Römer, Christian Schmidt, Ursula van Rienen +1
Uncertainty quantification plays an important role in biomedical engineering as measurement data is often unavailable and literature data shows a wide variability. Using state-of-t…
Multiple Right-Hand Side Techniques in Semi-Explicit Time Integration Methods for Transient Eddy Current Problems
Jennifer Dutiné, Markus Clemens, Sebastian Schöps
The spatially discretized magnetic vector potential formulation of magnetoquasistatic field problems is transformed from an infinitely stiff differential algebraic equation system…
Modeling of Spatial Uncertainties in the Magnetic Reluctivity
Radoslav Jankoski, Ulrich Römer, Sebastian Schöps
In this paper a computationally efficient approach is suggested for the stochastic modeling of an inhomogeneous reluctivity of magnetic materials. These materials can be part of el…
An algorithmic comparison of the Hyper-Reduction and the Discrete Empirical Interpolation Method for a nonlinear thermal problem
Felix Fritzen, Bernhard Haasdonk, David Ryckelynck +1
A novel algorithmic discussion of the methodological and numerical differences of competing parametric model reduction techniques for nonlinear problems are presented. First, the G…
High Dimensional Uncertainty Quantification for an Electrothermal Field Problem using Stochastic Collocation on Sparse Grids and Tensor Train Decompositions
D. Loukrezis, U. Römer, T. Casper +2
The temperature developed in bondwires of integrated circuits (ICs) is a possible source of malfunction, and has to be taken into account during the design phase of an IC. Due to m…
