The 11th International Symposium on Electric and Magnetic Fields, EMF 2018, was hosted in Darmstadt and concluded on Friday. The purpose of the Symposium was 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. There were 95 participants from 19 countries and 3 invited talks. The participants gave 26 oral presentations, presented 53 posters and drank 700 cups of coffee. Already these numbers imply that the conference was a great success. Now, we are looking forward to meet our colleagues in Marseille for the next edition organized by André Nicolet
Computer Methods in Applied Mechanics and Engineering has accepted our paper on Isogeometric analysis and harmonic stator–rotor coupling for simulating electric machines with DOI 10.1016/j.cma.2018.01.047. The paper proposes Isogeometric Analysis as an alternative to classical finite elements for simulating electric machines. Through the spline-based discretisation it is possible to parametrise the circular arcs exactly, thereby avoiding any geometrical error in the representation of the air gap where a high accuracy is mandatory.
Update: get the paper for free before April 10, 2018 at authors.elsevier.com.
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 →
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 →

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 →
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!

According to a recent study of Prognos
Darmstadt is the city with the 9th highest potential
in Germany. In a similar study of IW Consult
Darmstadt was even number one. The reasons were similar, for example: many young and well educated inhabitants with background in mathematics, natural sciences or engineering. Wirtschaftswoche
said “Hier profitiert Darmstadt von seiner 1877 gegründeten Technischen Universität. Hinzu kommt die Sogwirkung auf High Potentials durch drei Fraunhofer-Institute und das GSI Helmholtzzentrum für Schwerionenforschung, das gerade den Bau eines gigantischen Teilchenbeschleunigers vorbereitet.
