This work proposes a two-way coupling between Smoothed Particle Hydrodynamics (SPH) model-based named DualSPHysics and Finite Element Analysis (FEA) method to solve fluid–structure interaction (FSI). Aiming at having computationally efficient solution via spatial adjustable resolutions for the two phases, SPH-FEA herein presented implements Euler–Bernoulli beam model, based on simplified model ...

This paper presents results obtained by numerical study of sloshing effects in medium sized rectangular tanks subjected to a long-period seismic excitation. The Smoothed Particle Hydrodynamics (SPH) method is used, and the wave displacement and pressure are analysed. The intensity of sloshing effects depends not only on the peak ground acceleration but also on the dominant frequency of ground m...

One of the computational challenges cluster formation simulations is resolving individual stars and simulating massive clusters with masses more than $10^4 M_{\odot}$ without gravitational softening. Combining direct $N$-body code smoothed-particle hydrodynamics (SPH) code, we have developed a new \textsc{ASURA+BRIDGE}, in which can integrate stellar particles We add feedback model for \HII reg...

We model a massless viscous disk using Smoothed Particle Hydro-dynamics (SPH) and note that it evolves according to the Lynden-Bell & Pringle theory (1974) until a non-axisymmetric instability develops at the inner edge of the disk. This instability may have the same origin as the instability of initially axisymmetric viscous disks discussed by Lyubarskij et al. (1994). To clarify the evolution...

In this paper, we present a multi-resolution smoothed particle hydrodynamics (SPH) method for modeling fluid-structure interaction (FSI) problems. By introducing different smoothing lengths and time steps, the spatial-temporal discretization is applied with resolutions fluid structure. To ensure momentum conservation at coupling, position-based Verlet integration scheme introduced. Furthermore,...

We present the implementation of a dust growth and fragmentation module in public Smoothed Particle Hydrodynamics (SPH) code PHANTOM. This is made available for use with this paper. The coagulation model considers locally monodisperse size distributions around single values that are carried by SPH particles. Along presentation model, tests, we showcase few typical circumstellar disc simulations...

Smoothed Particle Hydrodynamics (SPH) is a numerical method commonly used in Computational Fluid Dynamics (CFD) to simulate complex free-surface flows. Simulations with this mesh-free particle method far exceed the capacity of a single processor. In this paper, as part of a dual-functioning code for either central processing units (CPUs) or Graphics Processor Units (GPUs), a parallelisation usi...

This paper describes a simple model of a star where compressibility is retained but the gravitational force is replaced by a force between pairs which is directed along their line of centres and proportional to their separation. This force was analysed by Newton. It may be considered the simplest many body force because the system reduces to a set of independent particles moving in a harmonic o...
