Memory Layouts for GPU-Data Transfer Buffering in SPH
Mladen Ivkovic, Abouzied M. A. Nasar, Tobias Weinzierl +4
The rise in GPU compute speed has outpaced improvements in host-to-device memory transfer speeds, despite the advent of shared-memory superchips. Consequently, memory transfer time…
A high-order Fourier Continuation (FC)-based spectral incompressible Smoothed Particle Hydrodynamics (ISPH) scheme for general boundary conditions in wall-bounded domains
Meixuan Lin, Georgios Fourtakas, Benedict D. Rogers
In this paper, a high-order Fourier Continuation (FC) algorithm is introduced into the spectral smoothed particle hydrodynamics (SPH) scheme to simulate the wall-bounded incompress…
Learning Mesh-Free Discrete Differential Operators with Self-Supervised Graph Neural Networks
Lucas Gerken Starepravo, Georgios Fourtakas, Steven Lind +3
Mesh-free numerical methods provide flexible discretisations for complex geometries; however, classical meshless discrete differential operators typically trade low computational c…
Task-parallelism in SWIFT for heterogeneous compute architectures
Abouzied M. A. Nasar, Benedict D. Rogers, Georgios Fourtakas +4
This paper highlights first steps towards enabling graphics processing unit (GPU) acceleration of the task-parallel smoothed particle hydrodynamics (SPH) solver SWIFT. Novel combin…
Exploring Neural Network Surrogates for High-Order Mesh-Free Interpolants
Lucas Gerken Starepravo, Georgios Fourtakas, Steven Lind +2
Mesh-free numerical methods offer flexibility in the discretisation of complex geometries, showing significant potential for problems where mesh-based methods struggle. Although hi…
Divergence cleaning for weakly compressible smoothed particle hydrodynamics
Georgios Fourtakas, Renato Vacondio, Benedict D. Rogers
This paper presents a divergence cleaning formulation for the velocity in the weakly compressible smoothed particle hydrodynamics (SPH) scheme. The proposed hyperbolic/parabolic di…
Framework for uncertainty quantification of wave-structure interaction in a flume
Xiaoyuan Luo, Vijay Nandurdikar, Sangri-Yi +3
In this paper we propose a numerical procedure for the quantification of uncertainties in wave-structure interaction. We utilise the smoothed particle hydrodynamics (SPH) scheme fo…
State-of-the-art SPH solver DualSPHysics: from fluid dynamics to multiphysics problems
Jose M. Domínguez, Georgios Fourtakas, Corrado Altomare +10
DualSPHysics is a weakly compressible smoothed particle hydrodynamics (SPH) Navier-Stokes solver initially conceived to deal with coastal engineering problems, especially those rel…
