The fluid analysis noted as the limit of simulation and the particles with viscosity are provided by an analysis for a number of spheres.
When the particles apply a force to a body, the reaction force and torque are generated, and a dynamic system formed from them can move the body. The moving-particle semi-implicit (MPS) method is a computational method for the simulation of incompressible free surface flows. It is a macroscopic, deterministic particle method (Lagrangian meshfree method) developed by Koshizuka and Oka (1996). The MPS method is similar to the SPH (Smoothed-Particle Hydrodynamics) method (Gingold and Monaghan, 1977; Lucy, 1977) in both methods which provide approximations to the strong form of the partial differential equations (PDEs) on the basis of integral interpolate. However, the MPS method is applied to the simplified differential operator models solely based on a local weighted averaging process without taking the gradient of the kernel function. In addition, the solution process of MPS method obtained by a semi-implicit prediction-correction process differs to that of the original SPH method.
