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…

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…

Learning-based branching strategies for mixed-integer programming

Arne Schulze (Chair of Business administration, HSU) A Mixed-integer programming (MIP) model solved by the Branch-a-Bound (B&B) method is the main exact solution strategy in combinatorial optimization like in production and logistics. The aforementioned optimization problems are typically NP-hard to solve such that a vast amount of computation power is…

Molecular Monte Carlo simulations on GPUs

Philipp Marienhagen (Thermodynamics, HSU) Recently, it has become possible to combine accurate ab initio potentials with Monte Carlo simulations which allows the theoretical prediction of thermodynamic properties of fluids with an accuracy challenging the best experimental results. This requires the use of a combination of pair and nonadditive three-body potentials…

Enabling global sensitivity analysis of large-scale FEM models using QUEENS

Sebastian Brandstäter (Computer-Based Simulation, UniBwM) This project will enable variance-based global sensitivity analysis based on Sobol’s method for large-scale finite-element models within the research software QUEENS. QUEENS is a Python framework for multi-query analyses like uncertainty quantification and Bayesian inverse problems of large-scale simulation models. Its applications range from automating…
