Marking strategies for adaptive mesh refinement: An efficiency-focused benchmark study for steady solid and fluid mechanics problems
Oliver Wege, Kaan Atak, Marek Behr +1
Adaptive mesh refinement (AMR) is indispensable for efficient finite element analyses. However, its performance depends not only on the refinement itself but also on strategy to ma…
Quantum Lattice Boltzmann with Denoising Collision Operators
Trong Duong, Matthias Möller, Norbert Hosters
The Lattice Boltzmann method (LBM) is a well-established mesoscopic approach for simulating fluid dynamics by evolving particle distribution functions on discrete lattices. While t…
Adaptive Encoding Strategy for Quantum Annealing in Mixed-Variable Engineering Optimization
Fabian Key, Lukas Freinberger, Mayu Muramatsu +1
Mixed discrete-continuous optimization is central to engineering design, where discrete choices interact with continuous fields. These problems are difficult due to high-dimensiona…
Multiphase Flow Simulation of Blow-by and Fuel-in-Oil Dilution via the Piston Ring Pack Using the CFD Level-Set Method
Patrick Antony, Norbert Hosters, Marek Behr +4
Modern diesel engines temporarily use a very late post-injection in the combustion cycle to either generate heat for a diesel particulate filter regeneration or purge a lean NOx tr…
On the number of subproblem iterations per coupling step in partitioned fluid-structure interaction simulations
Thomas Spenke, Nicolas Delaissé, Joris Degroote +1
In literature, the cost of a partitioned fluid-structure interaction scheme is typically assessed by the number of coupling iterations required per time step, while ignoring the in…
A Data-driven Reduced Order Modeling Approach Applied In Context Of Numerical Analysis And Optimization Of Plastic Profile Extrusion
