For violent sloshing, the flow field becomes complicated and 3-D effect is non-negligible. In addition to the excitation direction, the wave can also propagate perpendicular to the excitation direction. Due to the superposition of waves from different directions, the impact pressure imposed on the wall of the tank may increase. In this paper, our in-house solver MPSGPU-SJTU based on moving particle semi-implicit (MPS) method coupled with GPU techniques is employed for the liquid sloshing simulation, to study the factors leading to the 3-D effect. Firstly, a series of sloshing simulations are carried out to validate the reliability of present solver. Then, the sensitivity of 3-D effect against some parameters, such as excitation frequency, dimensions of the tank and filling ratio, is checked through numerical simulations. Time histories of pressure obtained by 2-D and 3-D simulations are compared to judge the occurrence of 3-D effect. It concludes that effects of those parameters are all significant.

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.
