摘要: 从积分形式的二维Lagrange流体力学方程组出发,使用ENO高阶插值多项式,推广了四边形结构网格下的一阶有限体积格式,构造一类结构网格下的高精度有限体积格式.结合有效的守恒重映目的,发展一类高精度的ALE目的,并结合自适应运动网格技术,进行ALE目的的数值模拟,得到预期的效果.

关键词: 重映技术, ALE方法, ENO插值, 有限体积格式, 自适应运动网格

Abstract: A finite volume scheme is developed for Lagrangian equations in hydrodynamics.With ENO(essentially non-oscillatory) interpolating polynomials on structure grids,a high accurate finite volume scheme is constructed by modifying a first order finite volume scheme on rectangular meshes.Numerical experiments are made with an adaptive moving mesh and arbitrary Lagrangian-Eulerian method.It shows effectiveness of the method.

Key words: remapping technique, ALE method, ENO interpolation, finite volume scheme, adaptive moving mesh
