Auf der Tagung des deustchen Mathematikerverbandes habe ich einen Vortrag zum “Mehrskalenverfahren für die Feld- und Netzwerkkopplung” gehalten: es wurden vor allem Mehrskalenverfahren in der Zeit für die schwachgekoppelte Simulation von räumlichverteilten elektromagnetischen Bauteilen mit elektrischen Netzwerken besprochen.

Next term the chair of numercial analysis, Bergische Universität Wuppertal, offers a lecture on Computational Magnetics. The aim is to develop an Octave software package to simulate magnetoquasistatic fields.
All the typical tasks of applied mathematics will be covered: modeling, software design, coding, testing, simulation und visualization.
I have written a simulation package FIDES to test multi rate time integration in coupled electromagnetic field and electric circruit equations. The package is part of the COMSON Demonstrator Platform, using OCTAVE as its interpreter.
Recently I wanted to visualize my results. I used ffmpeg to produce a movie from several plots of the flux distribution inside a transformer.
I’m back from the SCEE 2008 (Scientific Computing in Electrical Engineering) Conference in Espoo, Finland.The picture on the left is given to illustrate my coupling approach during my talk about circuits refined by 3-D conductor models. The circuit is given in terms of the modified nodal analysis and the field is discretized by the finite integration technique. The coupled system is introduced and analyzed; numerical results are obtained by co-simulation (“weak coupling”) and monolithic coupling (“strong”). The basic ideas are taken from my master thesis, but there are new additional theoretical and numerical results.

This is my thesis on computational electromagnetics, from the abstract:
Continue reading ‘Master-Thesis’
Electric 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.
