GPU-Accelerated ILES of Weakly Compressible Flows Using a Galerkin–Boltzmann Formulation Ata, Onur; Aygün, Atakan; Karakuş, Ali (2026-06-03) We present a high-order implicit large-eddy simulation (ILES) approach for nearly incompressible flows based on a nodal discontinuous Galerkin (DG) discretization of the continuous Boltzmann equations. The compact, low-dis...
GPU Accelerated Discontinuous Galerkin Solutions of Galerkin-Boltzmann Formulations for Nearly Incompressible Flows on Moving Meshes Aygün, Atakan; Ata, Onur; Karakuş, Ali (2026-03-06) In this talk, we introduce an arbitrary Lagrangian-Eulerian (ALE) formulation of the Galerkin-Boltzmann method, which recovers the Navier–Stokes equations in the nearly incompressible regime. A perfectly matched laye...
Physics-Informed Neural Networks for Heat Transfer and Fluid Flow problems Aygün, Atakan; Ata, Onur; Karakuş, Ali (2025-05-21) Physics-informed neural networks (PINN) have emerged as a viable alternative to the classicalnumerical methods while solving partial differential equations. Their ability to obtain the solutionwithout generating any mesh o...
Parallel Adaptive Mesh Refinement Algorithms on GPUs for Unstructured Grids Ata, Onur; Karakuş, Ali (2025-03-05) Adaptive mesh refinement (AMR) is a technique used to increase the spatial resolution of specific regions within the spatial domain of a simulation. It is useful in large-scale simulations to achieve a more computationally...
