Three papers from us on novel methods for time domain simulation of electromagnetic phenomenas have been published last week:
- ParaExp using Leapfrog as Integrator for High-Frequency Electromagnetic Simulations in: Radio Science. doi: 10.1002/2017RS006357.
- Solving nonlinear circuits with pulsed excitation by multirate partial differential equations in IEEE Transactions on Magnetics. doi: 10.1109/TMAG.2017.2759701.
- Parallel-in-time Simulation of Eddy Current Problems using Parareal in IEEE Transactions on Magnetics. doi: 10.1109/TMAG.2017.2763090.

From September 21st-22nd experts from CERN, Geneva and Tampere University of Technology, Finland and Technische Universität Darmstadt, Germany meet at the Graduate School CE, Darmstadt. They discuss models and methods for the simulations of transient effects in superconducting magnets and circuits. The key feature of the STEAM framework is the co-simulation of numerical models.

We published a first preprint at arXiv
on our research on Isogeometric BEM for Superconducting Cavities (DFG SCHO 1562/3-1
and KU 1553/4-1
). In cooperation with the Computational Mathematics
group in Basel we discuss the usage of higher order B-splines in view of regularity requirements, convergence of the solution within the domain and multipole compression techniques. Continue reading →
Our paper on “Optimized Field/Circuit Coupling for the Simulation of Quenches in Superconducting Magnets” has been accepted by the IEEE Journal on Multiscale and Multiphysics Computational Techniques
. The paper proposes an optimised waveform-relaxation approach for the simulation of magnetothermal transients in superconducting magnets. The work has been carried in the framework STEAM together with CERN.

From the press release: “Ein wichtiges Etappenziel für den Ausbau des Lichtenberg-Hochleistungsrechners ist geschafft: Der Wissenschaftsrat hat während seiner Frühjahrssitzungen das TU-Vorhaben „Lichtenberg II“ für die Förderung im Bund-Länder-Programm Forschungsbauten empfohlen. Beantragt sind 15 Millionen Euro, über die die Gemeinsame Wissenschaftskonferenz von Bund und Ländern Ende Juni entscheiden wird.”
Update. Funding is granted: “Lichtenberg II für die Spitzenforschung TU erhält 15 Millionen Euro von Bund und Land für Hochleistungsrechner” Continue reading →
Abele Simona and Luca Bonaventura from MOX, Politecnico di Milano will talk on 13 Mar 2017, 16:15–17:45 in S2|17-103 about Numerical approximation of charged particle motion in magnetic quadrupoles.
Our paper on “Simulation of Electro-Thermal Transients in Superconducting Accelerator Magnets with COMSOL Multiphysics” (authors: L. Bortot, M. Maciejewski, M. Prioli, A.M. Fernandez Navarro, S. Schöps, I. Cortes Garcia, B. Auchmann, and A.P. Verweij) is currently featured on the COMSOL blog
Today, computational engineering students and several colleagues from our work group of computational electromagnetics made an excursion to the GSI Helmholtzzentrum für Schwerionenforschung
. We visited the ion sources, the linear accelerator, the control room and we had a look to the prototype of the Super-FRS Magnet
of the FAIR project
. Thanks to the GSI for the tour and the important research that you do!
