The Moving Particle Semi-Implicit (MPS) method, a particle-based approach within computational fluid dynamics, underwent development and modification to effectively model the behavior of solid particles. To address phenomena associated with solid particles, the traditional viscosity calculation term was replaced with a friction calculation term that accounts for accumulated weight effects. The resulting program was employed to simulate the behavior of soil in a seabed penetration scenario. Subsequently, numerical outcomes were compared with corresponding experimental results to validate the efficacy of the newly developed approach.
