New article published in SISC

SIAM Journal on Scientific Computing (image taken from

Andreas Bartel, Markus Brunk, Michael Günther, and I have published a new article in the current issue 35(2) of SIAM’s Journal of Scientific Computing (Section: Computational Methods in Science and Engineering). The paper discusses dynamic iteration for coupled problems of electric circuits and distributed devices.

Sebastian's Poster at SCEE 2010

SCEE Poster Presentation

The 8th conference on Scientific Computing in Electrical Engineering was held in Toulouse, organized by Onera. My contribution was a poster on “Multirate Time Integration of Field/Circuit Coupled Problems by Schur Complements” and I was co-author of the talk on “A modeling based preconditioned dynamic iteration scheme for coupled circuit-device problems” given by Markus Brunk.

This is my thesis on computational electromagnetics, from the abstract:

3D Transformer ModelElectric circuits contain devices that exhibit multi-physical effects. We may think of electric or magnetic, but also thermal effects. Traditionally these devices are idealized and only one effect is considered, while the others are disregarded. This yields simple laws that mathematically express their transient behaviour, but does not conform to reality. So sometimes these models are not accurate enough and one wants to simulate a particular device with a refined model. We shall present such a refined modelling approach for electromagnetic devices in this treatise.
