Mike Botchev is visiting Darmstadt
Mike Botchev from the Keldysh Institute of Applied Mathematics, Russian Academy of Sciences, Moscow is visiting TU Darmstadt from August 1st to 2nd. He speaks on Thurday from 10:00–11:30 in S2|17-103 on “Solving Maxwell’s equations in time: from Yee splitting to Krylov exponential methods“. A new Centre for Computational Engineering at TU Darmstadt
In the process of establishing Computational Engineering (CE) as an independent and interdisciplinary scientific research at TU Darmstadt a new Centre for Computational Engineering was established. It is integrated into the structure of the university as an institutionalized cross-sectional area, orthogonally to the existing departments. The centre gathers all research and teaching activities within CE (undergraduate teaching, graduate school and research activities). More information (in German) can be found in TU Darmstadt’s news journal hoch3. How to get Octave 4.4.0 for macOS with GUI
The macOS package manager Homebrew ships with Octave 4.4 but it links to Apple’s proprietary BLAS implementation, the QT graphical user interface is not supported and the ode15 solvers are broken due to Octave’s outdated sundials 2.x dependency. However, there are two alternatives:
If you prefer a quick and easy solution, then go to octave-app.org and download the disk image that is being put together by apjanke and me. On the other hand, if you want to compile it by yourself (including all necessary patches) then follow the instructions below and hope for the best…

ECMI 2018 in Budapest
The 20th European Conference on Mathematics for Industry concluded on June, 22nd in Budapest, Hungary. The conference series is devoted to enforce the interaction between academy and industry, leading to innovations in both fields. These events have attracted leading experts from business, science and academia, and have promoted the application of novel mathematical technologies to industry. We organized a minisymposium on “Simulation, Optimization and Uncertainty Quantification of Field/Circuit Problems for E-Mobility Applications” and contributed three scientific talks
- Kulchytska-Ruchka, Iryna ; Schöps, Sebastian ; Gander, Martin J. ; Niyonzima, Innocent : Convergence analysis of Parareal for systems with discontinuous inputs.
- Cortes Garcia, Idoia ; De Gersem, Herbert ; Schöps, Sebastian : Generalised elements for the analysis of field/circuit coupled systems.
- Bontinck, Zeger ; Corno, Jacopo ; Schöps, Sebastian ; De Gersem, Herbert : Iso-Geometric Analysis as a Tool for Simulating Electrical Machines.
Festkolloquium “Numerische Mathematik in der Technischen Simulation” zu Ehren von Peter Rentrop
Gestern fand in Wuppertal das Festkolloquium “Numerische Mathematik in der Technischen Simulation” anlässlich des 70. Geburtstages von Prof. Peter Rentrop statt. Als “Descendant” (akademischer Enkel) war ich als Redner eingeladen und habe über “Coupled Differential Algebraic Equations – From Electric Networks to CERN’s Quench Protection System” vorgetragen.

In seinem abschließenden Vortrag zeigt Sebastian Schöps Möglichkeiten auf, wie Algorithmen und Berechnungen tatsächlich zum Einsatz kommen. Zum Beispiel könne mit Programmen simuliert werden, welche Schäden für die Gesundheit der Menschen entstehen, wenn sie permanent mit dem Handy am Ohr durch die Welt spazieren – ganz ohne Versuche direkt am Menschen.Tatsächlich simuliert man nicht die Schäden, sondern die Erwärmung (oder noch genauer die Energiedeposition) als “multiphysikalisches Problem”, siehe z.B. die Veröffentlichung aus 2002 von Gjonaj, Bartsch, Clemens, Schupp, Weiland. Simulation oder nicht, es gibt bisher keinen wissenschaftlichen Nachweis über Schäden. Die aktuellen Grenzwerte und viele weitere Informationen zum Thema findet man z.B. beim Informationszentrum Mobilfunk.

How to get Octave 4.4 for macOS
Octave 4.4 is a major new release with many new features, better compatibility with Matlab, and many new and improved functions.
Mac users can get a first binary (dmg) for testing from here. Please report issues at the mailing list. Homebrew users should soon be able to get Octave from https://github.com/dpo/homebrew-openblas (pull request #61).

The International Symposium on Electric and Magnetic Fields 2018 is over
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 and co-workers.
