During September I will be out of office (Wuppertal). I will be a guest at the Wave Propagation and Signal Processing Research Group of the Katholieke Universiteit Leuven, Kortrijk, thanks to my DAAD grant.

The Symposium on Electromagnetic Phenomena in Nonlinear Circuits (EPNC) 2010 was this year in Essen. – A stone’s throw from Wuppertal. I gave another talk on co-simulation. Here the method was applied to an induction motor, as shown in the figure on the right. The coupling is given by extracted inductances, similarily to the method presented at the Compumag 2009. This time the focus was on signal processing; the waveforms are smoothed to allow for large time steps.
My institute organizes from July 26-30, 2010 the next European Conference on Mathematics for Industry (ECMI). The conference is following up ECMI – 2008 in London, UK. As all ECMI conferences, ECMI 2010 will emphasize the role of mathematics as a unique overarching industrial resource.
The registration is open from January, 10th.
Compumag 2009 Plenary
The given application is a multirate framework for the efficient simulation of field/circuit coupled problems. Within this framework, a guarantee for convergence and stability was given by PDAE analysis. It was shown that different time step sizes in different parts of the model can be automatically chosen according to the problem’s dynamics. Finally a finite element model of a transformer coupled to a circuit was given to illustrate the efficiency of the multirate method.
The talk was awarded with a COMPUMAG best paper commendation.

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.
