一种基于物质点法的熔冰仿真方法
A simulation method for melting ice based on material point method
摘要
Abstract
In order to solve the problem of ice penetration caused by Lagrangian method,a method of ice penetration simulation based on material point method was proposed.Firstly,each Lagrangian particle in Euler space is regarded as an aggregate of solid-liquid two-way coupling to achieve a smooth transition from solid to liquid phase.Secondly,the thermal energy is calculated on the material point method background grid and the temperature linear system of the phase transition process is solved by pretreated conjugate gradient method.Finally,the latent heat phenomenon is treated,and the virtual water model is introduced to realize the simulation of the external flow phenomenon of ice by limiting the movement of the virtual water.The experimental result shows that this method can not only use material point method method to deal with the self collision advantage to solve the interpenetration,but it also simulates the real latent heat process of water flow phenomenon.关键词
