Magnetic Field Conforming Multiscale Formulations for Locally-Confined Nonlinear Eddy Current Problems Using the FE-HMM Method
Innocent Niyonzima, Gérard Meunier, Antoine Marteau +4
Magnetic composites used for the conversion of electrical energy often incorporate ferromagnetic inclusions insulated from each other to mitigate eddy current losses. Numerical mod…
Implementation of a cathode directed streamer model in Air under different voltage stresses
F Boakye-Mensah, N Bonifaci, R Hanna +1
To find a viable alternative to SF6 with growing climate change regulations, proper evaluation of alternatives such as compressed air ought to be done. For medium voltage applicati…
Modeling and simulation of nonlinear electro-thermo-mechanical continua with application to shape memory polymeric medical devices
Innocent Niyonzima, Yang Jiao, Jacob Fish
Shape memory materials have gained considerable attention thanks to their ability to change physical properties when subjected to external stimuli such as temperature, pH, humidity…
A New Parareal Algorithm for Problems with Discontinuous Sources
Martin J. Gander, Iryna Kulchytska-Ruchka, Innocent Niyonzima +1
The Parareal algorithm allows to solve evolution problems exploiting parallelization in time. Its convergence and stability have been proved under the assumption of regular (smooth…
Multiscale Finite Element Modeling of Nonlinear Magnetoquasistatic Problems Using Magnetic Induction Conforming Formulations
Innocent Niyonzima, Ruth V. Sabariego, Patrick Dular +2
In this paper we develop magnetic induction conforming multiscale formulations for magnetoquasistatic problems involving periodic materials. The formulations are derived using the…
Parallel-In-Time Simulation of Eddy Current Problems Using Parareal
Sebastian Schöps, Innocent Niyonzima, Markus Clemens
In this contribution the usage of the Parareal method is proposed for the time-parallel solution of the eddy current problem. The method is adapted to the particular challenges of…
ParaExp using Leapfrog as Integrator for High-Frequency Electromagnetic Simulations
Melina Merkel, Innocent Niyonzima, Sebastian Schöps
Recently, ParaExp was proposed for the time integration of linear hyperbolic problems. It splits the time interval of interest into sub-intervals and computes the solution on each…
Waveform Relaxation for the Computational Homogenization of Multiscale Magnetoquasistatic Problems
Innocent Niyonzima, Christophe Geuzaine, Sebastian Schöps
This paper proposes the application of the waveform relaxation method to the homogenization of multiscale magnetoquasistatic problems. In the monolithic heterogeneous multiscale me…
An Application of ParaExp to Electromagnetic Wave Problems
Melina Merkel, Innocent Niyonzima, Sebastian Schöps
Recently, ParaExp was proposed for the time integration of hyperbolic problems. It splits the time interval of interest into sub-intervals and computes the solution on each sub-int…
