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.

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”.

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.

Talk on the simulation of electrical machines by Lars Kielhorn

logo_tailsitDr. Lars Kielhorn from TailSiT GmbH, Graz (Austria) talks on 25 Jul 2016, 16:15–17:45 (room S4|10-314) in the seminar on Computational Engineering. Abstract: Electrical machines commonly consist of moving and stationary parts, e.g., an electric motor features a rotor and a stator. If volume based numerical schemes such as the Finite Element Method (FEM) are applied the electromagnetic simulation of such devices is a challenging task since the variation of the geometrical configuration needs to be incorporated into the numerical scheme.

Compile ONELAB on the Mac

ONELAB is an interface to finite element software, i.e., Gmsh and GetDP, for engineering applications. Homebrew science has been updated such that you can easily compile your own build on the Mac (after having installed brew):

> brew tap homebrew/science
> brew install gmsh --HEAD --with-fltk --with-petsc --with-slepc --with-opencascade
> brew install getdp --HEAD --with-petsc --with-slepc
