Benchmark cases for gradient-based optimization in linear elastic solid mechanics using lattice Boltzmann methods
Johannes L. Grafen, Florian Kaiser, Stephan Simonis +2
Gradient-based optimization (GBO) of problems constrained by partial differential equations is central to parameter identification and structural design in solid mechanics. Lattice…
Mean-Flow Adjoint Sensitivity Analysis of Unsteady Flow Around Porous Cylinders Using a Homogenized Lattice Boltzmann Method
Shota Ito, Johannes L. Grafen, Fedor Bukreev +2
Adjoint-based sensitivity analysis is an indispensable tool for large-scale fluid-dynamic design and distributed control problems, yet its application to unsteady and turbulent flo…
Micrometer-scale displacement and thickness sensing using a single terahertz resonant-tunneling diode
Li Yi, Shota Ito, Chao Tang +5
Resonant tunneling diodes (RTDs) support room-temperature terahertz (THz) oscillation and simultaneous THz-band detection, enabling compact monostatic THz sensors for practical and…
Efficient Wall-Modelled Large Eddy Simulation of Rotors using Homogenized Lattice Boltzmann Methods
Adrian Kummerländer, Shota Ito, Maximilian Schecher +4
Accurately capturing the dynamic forces acting on rotors as well as their wake effects presents a significant challenge for computational fluid dynamics (CFD) due to high Reynolds…
OpenLB-UQ: An Uncertainty Quantification Framework for Incompressible Fluid Flow Simulations
Mingliang Zhong, Adrian Kummerländer, Shota Ito +3
Uncertainty quantification (UQ) is crucial in computational fluid dynamics to assess the reliability and robustness of simulations, given the uncertainties in input parameters. Ope…
Large-Scale Simulations of Turbulent Flows using Lattice Boltzmann Methods on Heterogeneous High Performance Computers
Adrian Kummerländer, Fedor Bukreev, Yuji Shimojima +2
Current GPU-accelerated supercomputers promise to enable large-scale simulations of turbulent flows. Lattice Boltzmann Methods (LBM) are particularly well-suited to fulfilling this…
A Prefixed Patch Time Series Transformer for Two-Point Boundary Value Problems in Three-Body Problems
Akira Hatakeyama, Shota Ito, Toshihiko Yanase +1

Low-Thrust Many-Revolution Trajectory Design Under Operational Uncertainties for DESTINY+ Mission
Naoya Ozaki, Yuki Akiyama, Akira Hatakeyama +3
DESTINY+ is a planned JAXA medium-class Epsilon mission from Earth to deep space using a low-thrust, many-revolution orbit. Such a trajectory design is a challenging problem not on…
OpenLB User Guide: Associated with Release 1.6 of the Code
Adrian Kummerländer, Samuel J. Avis, Halim Kusumaatmaja +18
OpenLB is an object-oriented implementation of LBM. It is the first implementation of a generic platform for LBM programming, which is shared with the open source community (GPLv2)…
