How to get GNU Octave running on macOS with GUI

Gnu-octave-logo Currently, the best option to install Octave on macOS with a stable graphical user interface is via homebrew (sorry macports). Get the latest formula from my repository

brew tap schoeps/homebrew-science
pin the repository
brew tap-pin schoeps/homebrew-science
install a development version of octave (with GUI and java)
brew install octave --HEAD --with-qt --with-java

First results on fast high-order IGABEM

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.

Compumag 2017 – Best Poster Award

Compumag 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”.

EMF 2018 in Darmstadt

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 →

New Paper on Co-Simulation for Quench Protection at CERN

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.
