Matrix-Free & GPU Based FEM Simulations In Nonlinear Optics

Salah Eddine Zaidi (HSU/UniBw H) & Prof. Dr. Markus Bause (HSU/UniBw H) The efficient and reliable simulation of electromagnetic wave propagation is desirable for elucidation of physics and design optimization in nonlinear optics. A combination of explicit finite difference schemes and finite element methods are used for the temporal and…

Non-blocking communication for immersed boundary method applied in high-fidelity FSI simulations

Prof. Dr.-Ing. Michael Breuer (HSU/UniBw H), Dr. Guillaume De Nayer (HSU/UniBw H) & Khaled Boulbrachene (HSU/UniBw H) The in-house CFD solver FASTEST-3D, based on the Arbitrary Lagrangian–Eulerian (ALE) formulation, is designed for multi-physics simulations of turbulent flows. To address a new class of fluid-structure interaction (FSI) problems, this Fortran solver…

Modelling Newtonian Noise with NGSolve (DASHH, 2025–2028)

Paul Ophardt (HSU/UniBw H) & Prof. Dr. Katharina-Sophie Isleif (HSU/UniBw H) In order to achieve the design sensitivity of the next-generation gravitational wave detector, the Einstein Telescope, improved modelling of Newtonian noise is required. Newtonian noise is caused by gravitational perturbations arising from density fluctuations, in particular those induced by seismic…
