摘要: 有限体积法(FVM)是集有限差分法和有限元方法之优点而发展起来的一种新的数值方法.首先利用守恒问题给出FVM的基本概念和基本过程,接下来就间断解问题的求解进一步介绍了FVM的一些比较活跃的构造方法,并给出了用其中几个方法模拟二维溃坝问题的数值结果,然后按问题分类介绍了FVM数值方法和实际应用的进展,最后介绍了FVM理论分析的一些进展.

Abstract: A speedily developed numerical method called as finite volume method (FVM),which possesses both merits of finite difference method and finite element method,is devoloped.The construction of FVM for conservation laws is introduced.Especially,some efficient and successful schemes for solving the discontinuous problems are discussed in detail.Moreover,several numerical results of simulation of 2D dam break problem are given.Finally,a summary of advances in numerical applications and theoretical analysis of FVM is presented.

Key words: finite volume method, discontinuous, high resolution method, applications
