本文综述了任意拉格朗日欧拉(ALE)方法在一般多边形网格上模拟复杂几何结构中高速可压缩多材料流动的最新进展。我们只考虑了间接ALE方法，它包括三个关键阶段：拉格朗日阶段，在该阶段中，解和计算网格被更新；重分区阶段，在该阶段中，计算网格的节点被移动以提高网格质量；以及重映射阶段，在该阶段中，拉格朗日解被转移到重分区网格中。
This paper reviews recent developments in Arbitrary Lagrangian Eulerian (ALE) methods for modeling high speed compressible multimaterial flows in complex geometry on general polygonal meshes. We only consider the indirect ALE approach which consists of three key stages: a Lagrangian stage, in which the solution and the computational mesh are updated; a rezoning stage, in which the nodes of the computational mesh are moved to improve grid quality; and a remapping stage, in which the Lagrangian solution is transferred to the rezoned mesh.
