Numerical Simulation of Multidirectional Waves With Full-Spectrum Using DualSPHysics

Volume 9: Rodney Eatock Taylor Honoring Symposium on Marine and Offshore Hydrodynamics; Takeshi Kinoshita Honoring Symposium on Offshore Technology, 2019
Abstract The numerical model for circular wave basin were developed using DualSPHysics based on Smoothed Particle Hydrodynamics to generate short-crested wave. The recreation of short-crested wave was achieved using Pierson Moskowitz spectrum and cosin2s spreading function with spreading value s.

Extending DualSPHysics with a Differential Variational Inequality: modeling fluid-mechanism interaction

Applied Ocean Research, 2018
Abstract This work details the coupling of a Smoothed Particle Hydrodynamics (SPH) fluid solver with a general-purpose Differential Variational Inequality (DVI) based non-smooth multibody dynamics solver, allowing for efficient and accurate modeling of fluid-mechanism interactions, an ubiquitous scenario in natural and industrial settings.

Long-crested wave generation and absorption for SPH-based DualSPHysics model

Coastal Engineering, 2017
Abstract The present work presents a fully comprehensive implementation of wave generation and active wave absorption for second-order long-crested monochromatic and random waves in a WCSPH-based (Weakly Compressible Smoothed Particle Hydrodynamics) model. The open-source code DualSPHysics is used for the scope.

Landslide‐generated wave hazard prediction based on multiphase flow model of DualSPHysics

Computer Animation and Virtual Worlds, 2019
AbstractBecause involving a large number of discrete particles interacting with water, simulating the fluid–solid coupling problem of landslide‐generated waves in a virtual environment is very difficult. This paper employs the DualSPHysics multiphase flow model to relatively easily simulate the dynamics of landslide‐generated waves in large scales.

DualSPHysics, new GPU computing on SPH models

2011
The capacity of a single processor is insufficient torun huge 3D simulations with Smoothed ParticleHydrodynamics (SPH) methods. Here we present thedevelopment of a new code named DualSPHysics that can beexecuted either on either Central Processing Units (CPU) oron Graphics Processor Units (GPUs).

Survivability of floating moored offshore structures studied with DualSPHysics

2018
The open-source code DualSPHysics is here applied to simulate the interaction of sea waves with floating and offshore structures, which are typically moored to the sea bottom, such as vessels, boats and wave energy converter (WEC) devices. The goal is to employ DualSPHysics to study their survivability under high energetic sea states, obtaining the ...

Capturing wave energy converter's extreme response: Experimental validation of DualSPHysics and STAR CCM+

Validating numerical models against their physical realizations is an integral aspect, very essential for their development and a reliable assessment of their accuracy. This study focuses on comparing two different approaches: the open-source DualSPHysics, and the commercial software STAR CCM+, which have emerged as high-fidelity tools in evaluating ...
