These properties have made waves modeling one of the most complicated computational<br />problems. In this research a Lagrangian, multiphase, meshless and three dimensional method called<br />MP-MPS (Multi Phase Moving Particle Semi-implicit) have been developed based on the MPS<br />method. The MPS method is applicable in solving turbulent flow equations such as prorogating near<br />shore waves. In the multi phases model of MP-MPS the three dimensional and viscous equations have<br />been extended for three phases of gas, liquid and solid. In this way different phase’s counteraction<br />effect have been exerted in the equations by some variables, so the phase changes are modeled<br />synchronically. The dam breaking and wave propagating problems have been applied to show the<br />ability and accuracy of the model. The results have been compared against experimental and analytical<br />models. Comparison of model results against applied methods of primary researches represents the<br />accuracy and applicability of modified methods and algorithms deployed in the developed model. https://jhyd.iha.ir/article_85426_4a7d6903e1038e62204acbdf1b8ffc10.pdf
