New paper on isogeometric analysis of electrical machines
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.

How to compile GNU Octave with OpenBLAS on macOS
The repository homebrew/science is dead, long live dpo/homebrew-openblas! We switched from Apples proprietary Accelerate framework to OpenBLAS, so free your numbers and compile Octave as follows
brew tap dpo/openblasPin the repository
brew tap-pin dpo/openblasNow, install a development snapshot of octave (with GUI and java)
brew install dpo/openblas/octave --devel --with-qt --with-javaMacOS and Linux users with HiDPI screen will enjoy improved plotting thanks to the fixes of jpswensen for bug #49053.
DFG genehmigt ParaMQS2
Die DFG hat den Fortsetzungsantrag ParaMQS2 – Parallele und explizite Verfahren für die Simulation von Wirbelstromproblemen (SCHO1562/1-2) genehmigt. Es setzt die in Sachmittelbeihilfen CL14311-1 und SCHO1562/1-1 geförderten Vorarbeiten fort. Ziel des Forschungsvorhabens ist es numerisch effiziente parallele Algorithmen für die Berechnung von Wirbelstromproblemen zu entwickeln, die besonders gut geeignet sind für aktuelle heterogene, massiv parallele Rechnerarchitekturen. Da konventionelle implizite und neu entwickelte (semi-)explizite Zeitintegrationsverfahren für magnetoquasistatische Probleme ab einer gewissen Anzahl von Rechenkernen nicht mehr gut skalieren, sollen in diesem Forschungsvorhaben auch zeitparallele Algorithmen eingesetzt werden.
