Abstract: This paper presents an irregular wave simulation using the Moving Particle Semi-implicit (MPS) method. Irregular waves consist of component waves with a variety of frequencies and wave heights; however, a numerical model with sufficiently high energy conservation must be applied to reproduce them effectively in a numerical simulation. In general, conventional particle methods do not have sufficient energy conservation, and they cannot successfully realize irregular waves propagating a sufficiently long distance. Therefore, in this study, we propose an MPS-based numerical model with high energy conservation. We clarify that the standard algorithm of the original MPS method is not strictly based on the projection method and propose a modified algorithm to resolve this problem completely, namely Accurate Projection Algorithm (APA). The proposed model implementing APA and several enhanced MPS-based discretization schemes, including the Improved Dynamic Stabilization (IDS) scheme has high energy conservation. The model was verified and validated through three types of benchmark tests: a plane 2D oscillating drop test, a vertical 2D standing wave test, and a solitary wave test. Subsequently, we conducted an irregular wave simulation in a wave flume with a flat bottom. It was demonstrated that the proposed model can simulate irregular waves without wave height attenuation.
