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.

Recent Advances on Multiphysics Simulation of Accelerator Magnets within STEAM at CERN

New papers from the STEAM collaboration with CERN, presented at the 25th International Conference on Magnet Technology have been accepted for publication by IEEE

TU9 zur Kennzeichnung ingenieurwissenschaftlicher Studiengänge

Aus der TU9-Handreichung zur Kennzeichnung ingenieurwissenschaftlicher Studiengänge: “… methodische Vorgehensweisen, die unabhängig von einem spezifischen Anwendungsbereich einsetzbar sind und sich damit zu eigenen neuen Fächern entwickeln (z.B. Computational Engineering) und die traditionellen Ingenieurdisziplinen befruchten.” → Jetzt im Studiengang Computational Engineering in Darmstadt bewerben!
