The International Association of Applied Mathematics and Mechanics (Gesellschaft für Angewandte Mathematik und Mechanik: GAMM) has awarded me a “GAMM Junior” membership for the years 2012-2014.
GAMM Juniors sind DoktorandInnen oder junge Postdocs, die eine exzellente Masterarbeit oder Dissertation in der Angewandten Mathematik oder in der Mechanik geschrieben haben. Sie werden für 3 Jahre nominiert.
On Tuesday, September 27th I gave a talk at the Kleinheubacher Tagung 2011 of the German U.R.S.I. Comission.
The talk was on ‘Transient Magneto-Quasistatic Field Simulation Using Domain Decomposition with Semi-Implicit Time Integration’. This is a joint work together with Andreas Bartel and Markus Clemens from the Lehrstuhl für Numerische Analysis und Angewandte Mathematik and the Lehrstuhl für Theoretische Elektrotechnik, Bergische Universität Wuppertal, respectively.
A new journal article “Structural analysis of electrical circuits including magnetoquasistatic devices” (written together with Andreas Bartel and Sascha Baumanns) is finally online. Published in Applied Numerical Mathematics, Volume 61, Issue 12, December 2011, Pages 1257-1270. DOI: 10.1016/j.apnum.2011.08.004.

I am on vacation in Sønder Stenderup, Denmark: great weather, a nice beach and the sea.
Back on August, 8th.
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.
My Dissertation “Multiscale Modeling and Multirate Time-Integration of Field/Circuit Coupled Problems” is now submitted at the B.U. Wuppertal and K.U. Leuven. The defense is on May, 20th.
I give a seminar talk on Tuesday, 14 Dec 2010, 11:00-12:00 at K.U.Leuven, Dep. Computer Science, Celestijnenlaan 200A, lecture room 05.001.
