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.

Compumag 2009 Plenary

I attended the Compumag 2009 in Florianópolis supported by a travel grant from the DAAD (German Academic Exchange Service). At the conference I showed a nice application of my latest research on co-simulation (together with Andreas Bartel and Herbert De Gersem). The theory is based on the work of Arnold/Günther: “Preconditioned dynamic iteration for coupled differential-algebraic systems” published in BIT Numerical Mathematics.

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.
