Mixed-Precision Computing for Scientific Discovery: Formats, Co-Design, and Responsible Approximation
Emmanuel Agullo, Hartwig Anzt, Daniel Bauer +37
Reduced and mixed precision have moved from a niche optimization to a central design axis in scientific computing and engineering, driven by energy constraints, heterogeneous accel…
Thermodynamically consistent phase-field modeling and numerical simulation for reactive two-phase fluid-solid dynamics
Cedric Riethmüller, Lars von Wolff, Dominik Göddeke +1
We introduce a coupled Cahn-Hilliard Navier-Stokes model that governs the reactive two-phase dynamics of a system that consists of a fluid and a solid phase and prove its thermodyn…
Partitioned Coupling vs. Monolithic Block-Preconditioning Approaches for Solving Stokes-Darcy Systems
Jenny Schmalfuss, Cedric Riethmüller, Mirco Altenbernd +2
We consider the time-dependent Stokes-Darcy problem as a model case for the challenges involved in solving coupled systems. Keeping the model, its discretization, and the underlyin…
Bayesian inversion for electromyography using low-rank tensor formats
Anna Rörich, Tim A. Werthmann, Dominik Göddeke +1
The reconstruction of the structure of biological tissue using electromyographic data is a non-invasive imaging method with diverse medical applications. Mathematically, this proce…
A p-multigrid method enhanced with an ILUT smoother and its comparison to h-multigrid methods within Isogeometric Analysis
R. Tielen, M. Möller, D. Göddeke +1
Over the years, Isogeometric Analysis has shown to be a successful alternative to the Finite Element Method (FEM). However, solving the resulting linear systems of equations effici…
