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.
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.
