“…Recently, GPU acceleration has been increasingly applied in parallel computing of SPH. The application fields include computational fluid dynamics, geotechnical simulations, fluid structure interaction, and multibody dynamics . In this work, the parallelization is based on the Compute Unified Device Architecture (CUDA).…”

“…The GPU implementation of the whole computing process including neighbor search, particle interaction, and time integration is almost the same as that in Zhan et al, with the only difference on handling the motion of rigid bodies. As the translation and rotation of rigid bodies are dependent on the total forces and torques on each body, a summation operation is required for each bodies over all its particles.…”

“…A simple and intuitive way of modeling the soil‐body contact is to use boundary treatment methods, where soils are modeled as geomaterials and rigid bodies can be treated as boundaries. For example, various boundary treatment methods were employed to model fluid‐structure interaction in SPH . Similarly, some boundary treatment methods were applied to soil‐structure interaction, for example, Zhan et al and Neto et al used a similar extrapolated boundary particle method to model the granular flow impact on structures.…”

A smoothed particle hydrodynamics (SPH) framework for three-dimensional dynamic soil-multibody interaction modeling is presented, where both soils and rigid bodies are discretized using SPH particles. In the framework, soils are modeled using the Drucker-Prager model, while rigid bodies are considered with a multibody dynamics solver. A hybrid contact method suitable for three-dimensional simulations is developed to model the soil-body and body-body frictionless and frictional contacts, where contact forces are calculated based on ideal plastic collision and the unit normal/tangential vectors of the actual surface. Owing to its simplicity in contact detection and accuracy in contact force calculation, the hybrid contact method can be easily incorporated into SPH. Furthermore, graphics processing unit (GPU) parallelization is utilized to improve efficiency. The presented numerical framework and the hybrid contact method are validated using several examples. Numerical results are compared with analytical solutions and results from the literature. Furthermore, two three-dimensional simulations involving dynamic soil-multibody interaction are included to demonstrate the application.

“…These equations can generally be discretized on a 2-or 3-D grid by the use of well-established techniques such as the Finite Volume (FV) or Finite Element (FE) methods. With the advent of new and more powerful hardware, including Central Processing Unit (CPU) and Graphics Processing Unit (GPU), the efficiency and effectiveness of the aforementioned methodologies have improved significantly, allowing the study of real-life problems [7][8][9][10][11].…”

The Pont del Petroli is a dismissed pier in the area of Badalona, Spain, with high historical and social value. This structure was heavily damaged in January 2020 during the storm Gloria that hit southeastern Spain with remarkable strength. The reconstruction of the pier requires the assessment and characterization of the wave loading that determined the structural failure. Therefore, a state-of-the-art Computational Fluid Dynamic (CFD) code was employed herein as an aid for a planned experimental campaign that will be carried out at the Maritime Engineering Laboratory of Universitat Politècnica de Catalunya-BarcelonaTech (LIM/UPC). The numerical model is based on Smoothed Particle Hydrodynamics (SPH) and has been employed to simulate conditions very similar to those that manifested during the storm Gloria. The high computational cost for a full 3-D simulation has been alleviated by means of inlet boundary conditions, allowing wave generation very close to the structure. Numerical results reveal forces higher than the design loads of the pier, including both self-weight and accidental loads. This demonstrates that the main failure mechanism that led to severe structural damage of the pier during the storm is related to the exceeded lateral soil resistance. To the best of the authors’ knowledge, this research represents the first known application of SPH open boundary conditions to model a real-world engineering case.

“…The mesh-free particle-based (Lagrangian) methods, such as the smoothed particle hydrodynamics (SPH) (Gingold & Monaghan, 1977;Lucy, 1977) and the moving particle semi-implicit (MPS) (Koshizuka & Oka, 1996), are very effective to model violent freesurface flows with large interfacial deformation and fragmentations. These methods have been widely applied to solve FSI problems (Chikazawa et al, 2001) (Antoci et al, 2007) (Rafiee & Thiagarajan, 2009) (Amini et al, 2011) (Amaro Junior & Cheng, 2013) (Hwang et al, 2016) (Falahaty et al, 2018) (Khayyer et al, 2018) (Nasar et al, 2019) (Sun et al, 2019 (Wang et al, 2019) (Zhan et al, 2019) (Liu et al, 2020).…”
