LEDDS: Portable LBM-DEM simulations on GPUs
Raphael Maggio-Aprile, Maxime Rambosson, Christophe Coreixas +1
Algorithmic formulations of GPU programs provide a high-level alternative to device-specific code by expressing computations as compositions of well-defined parallel primitives (e.…

GPU-based compressible lattice Boltzmann simulations on non-uniform grids using standard C++ parallelism: From best practices to aerodynamics, aeroacoustics and supersonic flow simulations
Christophe Coreixas, Jonas Latt
Despite decades of research, creating accurate, robust, and efficient lattice Boltzmann methods (LBM) on non-uniform grids with seamless GPU acceleration remains challenging. This…

A note on the lattice momentum balance in the lattice Boltzmann interaction-framework
Francesca Pelusi, Matteo Lulli, Christophe Coreixas +2
In this note, we show how the exploitation of the lattice momentum balance condition allows to envisage an analytical procedure to define the lattice pressure tensor (LPT) for the…
