GCCE Poster Day

Prof. Dr.-Ing. Herbert De Gersem from TU Darmstadt will give a lecture on "Data-driven magnetic field simulation". 

• Date: 31.03.2026
• Time: 11:00 bis 12:30
• Location: Hörsaal i6, Inffeldgasse 25/D, 1. OG, 8010 Graz

Abstract: In standard finite-element methods, the behaviour of magnetic materials is represented by a material model, of which the parameters need to be retrieved from measurements by regression. As an alternative to this procedure, in the talk, I will develop and explain a finite-element method refraining from using a material model but considering the raw measurement data instead. Essentially, the technique amounts to minimising the distance between the material behaviour at the finite-element quadrature points and the measurement points, using a suitable norm in the so-called phase space. Physical constraints are enforced as symmetries in the phase space. The Maxwell equations are added as constraints by the Lagrange multiplier method. The data-driven magnetic field solver will be illustrated for examples from electrical engineering and accelerator technology.

Herbert De Gersem received the M.Sc. and Ph.D. degrees in electrical engineering from KU Leuven, Belgium, in 1994 and 2001. From 2001 to 2006, he was with TU Darmstadt, Germany as a postdoc. Since 2001, he is Associated Professor in Accelerator Physics at KU Leuven. Since 2014, he is Full Professor at the Institute for Accelerator Science and Electromagnetic Field, TU Darmstadt. His research interests include finite-element electromagnetic field simulation for electrotechnical devices and particle accelerators, as well as FDTD and FETD techniques for electromagnetic and ultrasonic wave propagation.

Assoc. Prof. Rolf Ryham (Fordham University, New York) will give a talk on Recent progress in the analysis of the Poisson-Nernst-Planck system.

• Date:  Wednesday, March 25th 2026
• Time: 17:00-18:00
• Place: Seminarraum Mechanik, Kopernikusgasse 24 IV NT04098

Abstract: The Poisson-Nernst-Planck system consists of a coupled system of parabolic and elliptic equations describing the diffusion and electromigration of charges and their electrical potential.  While well-posedness and long-term behavior for two-dimensional, bounded domains is well understood, the analysis faces significant difficulties in three and higher dimensions where weak solutions are merely found to be locally weakly differentiable.  The system, however, enjoys a so-called very weak formulation where, for example, properties like local boundedness can be gained from minimal assumptions.

Prof. Michael Vorländer from RWTH Aachen will give a lecture on Scattering and Diffraction Models for Outdoor Sound Propagation (in German) 

Date: 18.02.2026

Time: 11:00 - 12:30

Location: Hörsaal i6, Inffeldgasse 25d, 8010 Graz

Abstract: In the simulation of outdoor noise scenes using geometric methods, scattering and diffraction pose significant challenges. Standardized scattering parameters are too simplistic and cannot capture specific effects such as backscattering or other reflection patterns from periodic surface structures. Diffraction at individual edges can be approximated with good accuracy; however, the relevance of considering higher-order diffraction remains unclear. The lecture will discuss both scattering and diffraction effects as well as their implementation in geometric acoustics models.

Prof. Dr. rer. nat. Dr.-Ing. habil Michael Vorländer has been a professor at RWTH Aachen University since 1996 and has been emeritus since February 2025. His research focuses on auralization and acoustic virtual reality in their various applications in the fields of psychoacoustics, architectural acoustics, automotive engineering, and noise control. Michael Vorländer has published 3 books and 17 book chapters, 159 articles in professional journals, and has delivered 29 plenary lectures at international conferences. He has served as president of several professional societies, including the International Commission for Acoustics (ICA) from 2011 to 2013, the German Acoustical Society (DEGA) from 2016 to 2019, and the Acoustical Society of America from 2025 to 2026.
