Exploring Parallel-in-Time Approaches for Eddy Current Problems
Stephanie Friedhoff, Jens Hahne, Iryna Kulchytska-Ruchka +1
We consider the usage of parallel-in-time algorithms of the Parareal and multigrid-reduction-in-time (MGRIT) methodologies for the parallel-in-time solution of the eddy current pro…
A New Parareal Algorithm for Time-Periodic Problems with Discontinuous Inputs
Martin J. Gander, Iryna Kulchytska-Ruchka, Sebastian Schöps
The Parareal algorithm, which is related to multiple shooting, was introduced for solving evolution problems in a time-parallel manner. The algorithm was then extended to solve tim…
Sparse Representations for Uncertainty Quantification of a Coupled Field-Circuit Problem
Roland Pulch, Sebastian Schöps
We consider a model of an electric circuit, where differential algebraic equations for a circuit part are coupled to partial differential equations for an electromagnetic field par…
Systems of Differential Algebraic Equations in Computational Electromagnetics
Idoia Cortes Garcia, Sebastian Schöps, Herbert De Gersem +1
Starting from space-discretisation of Maxwell's equations, various classical formulations are proposed for the simulation of electromagnetic fields. They differ in the phenomena co…
Uncertainty Quantification For A Permanent Magnet Synchronous Machine With Dynamic Rotor Eccentricity
Zeger Bontinck, Oliver Lass, Herbert De Gersem +1
The influence of dynamic eccentricity on the harmonic spectrum of the torque of a permanent magnet synchronous machine is studied. The spectrum is calculated by an energy balance m…
A Structural Analysis of Field/Circuit Coupled Problems Based on a Generalised Circuit Element
Idoia Cortes Garcia, Herbert De Gersem, Sebastian Schöps
In some applications there arises the need of a spatially distributed description of a physical quantity inside a device coupled to a circuit. Then, the in-space discretised system…
