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 →
2017 took place in Daejeon (South Korea) from June 18-22, 2017. It is one of the most important conferences in the field of computational electromagnetics. Our other contributions were very well received (9 posters and 2 oral presentations). We received two awards, in particular Radoslav Jankoski has won a best poster award for his contribution “The Impact of Spatial Uncertainties in the Magnetic Reluctivity on the Field Quality of a Combined Function Magnet”.

The 11th International Symposium on Electric and Magnetic Fields, EMF 2018, will be held in Darmstadt (Germany) from 10 to 12 April 2018. The purpose of the Symposium is to throw a bridge between recent research advances in mathematical and numerical modelling of electromagnetic fields and the growing number of industrial problems requiring such techniques. Do not miss the chance to take part, the call for papers will open soon. Abstracts should be submitted by 24 November 2017! 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 →
I am proud to announce that DFG grants funding for our research on the simulation of superconducting cavities with isogeometric boundary elements “IGA-BEM”. The project is supervised by Stefan Kurz (KU 1553/4-1) and myself (SCHO1562/3-1). The aim of the joint project is the highly accurate simulation of resonant frequencies of superconducting cavities in particle accelerators. Since the simulation accuracy heavily depends on the geometry representation it will be described and discretized with Non-Uniform Rational B-Splines, which allow an exact description of the computer aided design.
Die TU Darmstadt unterstützt den March for Science offiziell als Institution – das hat das Präsidium in seiner jüngsten Sitzung beschlossen. Zu den weiteren Institutionen, die den March for Science unterstützen, zählen unter anderem die Alexander von Humboldt-Stiftung oder der Deutsche Akademischer Austauschdienst (DAAD).
