The book “Progress in Differential-Algebraic Equations” is available online and has just been published on SpringerLink:
This book contains the proceedings of the 8th Workshop on Coupled Descriptor Systems held March 2013 in the Castle of Eringerfeld, Geseke in the neighborhood of Paderborn, Germany. It examines the wide range of current research topics in descriptor systems, including mathematical modeling, index analysis, wellposedness of problems, stiffness and different time-scales, cosimulation and splitting methods and convergence analysis. In addition, the book also presents applications from the automotive and circuit industries that show that descriptor systems provide challenging problems from the point of view of both theory and practice.
The book contains nine papers and is organized into three parts: control, simulation, and model order reduction. It will serve as an ideal resource for applied mathematicians and engineers, in particular those from mechanics and electromagnetics, who work with coupled differential equations.
The article “On the convergence rate of dynamic iteration for coupled problems with multiple subsystems” (together with Andreas Bartel and Markus Brunk) has been accepted for publication in Journal of Computational and Applied Mathematics (JCAM).
The preprint can be found at the IMACM server in Wuppertal.
The paper “Extended Brauer Model for Ferromagnetic Materials: Analysis & Computation” (a joint work with Timo Hülsmann, Andreas Bartel and Herbert De Gersem) has been accepted for publication in COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering. It was also recently presented at SCEE 2012.Continue reading
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.Continue reading
The research during the winter term 2013 has been quite successful also thanks to my collaborators in Wuppertal and Leuven. The following papers will appear in upcoming volumes of IEEE Transactions on Magnetics:
- A Parallel FEM Matrix Assembly for Electro-Quasistatic Problems on GPGPU Systems (Eike Scholz, Sebastian Schöps, Markus Clemens)
- Reduction of Linear Subdomains for Non-Linear Electro-Quasistatic Field Simulations (Daniel Schmidthäusler, Sebastian Schöps, Markus Clemens)
- GPU Acceleration of Finite Differences in Coupled Electromagnetic/Thermal Simulations (Christian Richter, Sebastian Schöps, Markus Clemens)
- Quantification of Uncertainty in the Field Quality of Magnets Originating from Material Measurements (Andreas Bartel, Herbert De Gersem, Timo Hülsmann, Ulrich Römer, Sebastian Schöps, Thomas Weiland)
