STEAM Collaboration Meeting 2017

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.

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.

DFG Funds Research on Isogeometric BEM at TU Darmstadt

I am proud to announce that DFG grants funding for our research on the simulation of superconducting cavities with isogeometric boundary elements “IGA-BEM”. The project is supervised by Stefan Kurz (KU 1553/4-1) and myself (SCHO1562/3-1). The aim of the joint project is the highly accurate simulation of resonant frequencies of superconducting cavities in particle accelerators. Since the simulation accuracy heavily depends on the geometry representation it will be described and discretized with Non-Uniform Rational B-Splines, which allow an exact description of the computer aided design.

Winter excursion to GSI, Darmstadt

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!

International Congress on Industrial and Applied Mathematics 2015

http://www.iciam2015.cnThe International Congress on Industrial and Applied Mathematics (ICIAM) is held every four years and from August 10 to 14, 2015, mathematicians from around the world gathered in Beijing, China for the 8th ICIAM held at the China National Convention Center inside the Beijing Olympic Green. We have been presenting works on Multirate Time-Domain Simulation of Field/Circuit Coupled PWM Controlled Devices (together with Ruth Vazquez Sabariego and Johan Gyselinck) and Modelling of TESLA Cavities’ Eccentricity with Isogeometric Analysis (Jacopo Corno with Carlo de Falco). The poster presentation of the latter work has been recorded by ICIAM TV; there is also an interview of Prof. Annalisa Buffa talking about IGA.
