“…Similarly, Zhang et al [57] proposed a multi-resolution SPH method and simulated 2D fluid-structure interaction problems. Recently, Sun et al [58] applied the multi-resolution MPS-DEM method for a 2D FSI simulation, where the fluid was simulated with the multi-resolution MPS method and the structure was described by the DEM. Chen et al [59] proposed the multi-resolution SPH-FEM method, where the beam elements in FE were coupled with SPH particles and 2D FSI problems were simulated.…”

This work aims to propose an efficient MPS/FEM coupling method for the simulation of fluid–structure interaction (FSI), where the MPS and FEM are respectively employed to account for fluid flows and structural deformation. The main idea of our method is to develop a multi-scale multi-resolution MPS method for efficient fluid simulations in the context of MPS/FEM coupling. In the developed multi-scale MPS method, the fluid domain is discretized into particles of different resolutions before calculation, where particles close to the interest domain will be discretized into high resolution, while the rest are discretized into low resolution. A large particle interacting with small particles is divided into several small particles virtually, and weight functions are redefined to maintain the simulation stability. A bucket-sort-based algorithm is developed for the fast search of multi-resolution neighboring particles. The capacity of a newly proposed ghost cell boundary model is further enhanced, so as to accurately treat wall boundary problems with particles of different resolutions. On this basis, the multi-resolution MPS method is coupled with the FEM for FSI simulations. Finally, several numerical examples are conducted to demonstrate the accuracy and efficiency of the development method.

“…21 Nevertheless, since uniform spatial resolution is usually adopted in the fluid domain for large-scale FSI problems involving complex or thin structures, huge computational efforts associated with high-resolution models are demanded. In that case, some authors adopted multiresolution techniques, 22,23,24,25,26,27 in which high resolution is used only near the structures or local critical areas. However, these formulations are generally complex, especially for three-dimensional (3D) problems, and demand a considerable coding implementation effort.…”

A three-dimensional fluid-structure interaction solver based on an improved weakly compressible moving particle simulation (WC-MPS) method and a geometrically nonlinear shell structural model is developed and applied to hydro-elastic free-surface flows. The fluid-structure coupling is performed by a polygon wall boundary model that can handle particles and finite elements of distinct sizes. In WC-MPS, a tuning-free diffusive term is introduced to the continuity equation to mitigate nonphysical pressure oscillations. Discrete divergence operators are derived and applied to the polygon wall boundary, of which the numerical stability is enhanced by a repulsive Lennard-Jones force.Additionally, an efficient technique to deal with the interaction between fluid particles placed at opposite sides of zero-thickness walls is proposed. The geometrically nonlinear shell is modeled by an unstructured mesh of six-node triangular elements. Finite rotations are considered with Rodrigues parameters and a hyperelastic constitutive model is adopted. Benchmark examples involving free-surface flows and thin-walled structures demonstrate that the proposed model is robust, numerically stable and offers more efficient computation by allowing mesh size larger than that of fluid particles.

With the significant development of computer hardware, many advanced numerical techniques have been proposed to investigate complex hydrodynamic problems. This article aims to provide a detailed review of moving particle semi-implicit (MPS) techniques and their application in ocean and coastal engineering. The achievements of the MPS method in stability and accuracy, boundary conditions, and acceleration techniques are discussed. The applications of the MPS method, which are classified into two main categories, namely, multiphase flows and fluid-structure interactions, are introduced. Finally, the prospects and conclusions are highlighted. The MPS method has the potential to solve practical problems.
