Time-X project: TIME parallelization for eXascale computing and beyond

Nowadays digital twins are commonly designed and investigated in industry before physical products are manufactured. To construct such virtual prototypes multiobjective optimization of several key performance indicators from different physical domains is performed. For a wide range of applications, e.g., electric motors, high-fidelity transient simulations are necessary, as they allow […]

Electro-Thermal Modeling of High-Temperature Superconducting Coils and Magnets in Collaboration With CERN

Superconducting magnets are used in high-energy particle accelerators such as the Large Hadron Collider at CERN to exert electromagnetic forces on the particle beam. These forces keep the particles on a circular path by, e.g., bending the path of the beam and keeping it focused. High-temperature superconducting (HTS) materials are […]

AI-TWILIGHT: AI powered Digital Twin for lighting infrastructure in the context of front-end Industry 4.0

Over the last decades, LEDs have taken over the lighting industry. Their design is a multiphysical problem, involving mechanical, optical, electrical, and thermal components and considerations. All of these domains influence the operational behavior of LEDs, with the temperature having the largest impact on the lifetime of a given product. […]

Finite Element Parasitic Extraction and Sensitivity Analysis in Industry

Parasitic extraction is a key technique in electromagnetic compatibility analysis. It enables to extract the parasitic resistances, inductances, and capacitances from a CAD model, and thereby to asses the performance of the design in a joint circuit simulation in combination with its functional circuit elements. A sensitivity analysis of the […]

Modelling Ground Temperatures for the Climate Model LPJmL4

by Julia Niebsch Climate models are used to make predictions about the future development of the climate. These models use a variety of factors like aerial CO2 levels, sea temperatures and forestation to determine possible outcomes of the ongoing climate crisis. These physical and chemical processes can be described through […]

Mathematics for Ophtalmology

by Julia Shatokhina Optical coherence tomography (OCT) is a powerful interferometric technique providing non-invasive 3D imaging of sub-surface structures with resolutions on the micrometer scale. Significant developments of the OCT techniques in the recent decades were observed especially in biomedical applications. Thus, in ophthalmology the OCT imaging technique has revolutionized […]

Atmospheric Tomography at Keck Telescope

by Stefan Raffetseder Using measurements of multiple guide stars in different directions inan Adaptive Optics system leads to the problem of atmospheric tomogra-phy. Usually, this problem is solved by an inverse matrix operation, whichrequires O (n2) operations. Since the new generation of ground-based tele-scopes have a diameter of 30m and […]

A multigrid method for elasto-hydrodynamic contact simulations of radial slider bearing

by Michael Reichelt, Markus Windisch, Günter Offner, and Sarah Santner inETNA, Volume 54, pp. 355-369, 2021 Abstract The well-known Reynolds equation is typically used to compute the pressure distribution for elasto-hydrodynamic contacts of parts, as, for instance, in radial slider bearings. In order to resolve local pressure phenomena like edge […]
