I successfully defended my doctorate on “Multiscale Modeling and Multirate Time-Integration of Field/Circuit Coupled Problems” last Friday.

Update: The thesis is published in the subseries on electromagnetism of the Fortschritt-Berichte VDI and on the e-publication server of the Bergische Universität Wuppertal.

WPSP-Seminar at K.U. Leuven

I will present the results of my Ph.D.-thesis on Monday, May 16th 2011, 14:00 at the Katholieke Universiteit Leuven Campus Kortrijk.
The talk deals with multiscale models from electrical engineering, i.e., the electric network, the magnetoquasistaic field device and the drift-diffusion model of a semiconductor. Their structure, coupling and DAE-index are analyzed and furthermore multirate time-integration methods for the coupled problem are discussed. This is in particular the multirate Schur complement with an energy-based update scheme and the dynamic iteration approach. It will be shown by numerical examples that their application reduces significantly the computational costs in coupled simulations compared to the standard single-rate approach.
