无网格法理论及应用综述
首发时间:2009-05-13
摘要:传统的数值模拟方法都需要网格单元,网格的生成需要占用大量的计算时间,求解所需的数据量也较大。新兴的无网格方法摆脱了网格单元的限制,只需要节点信息,使前处理变得简单。本文对无网格方法的提出、发展和分类进行了综述,介绍了其在固体力学、材料力学方面的应用,并对其在流体力学方面的应用做了展望

Review of Gridless method theory and its application
Abstract:Grid cells are needed in traditional numerical simulation methods, which take a lot of time to produce, and need lots of data to compute. The new gridless method gets rid of the restrict of grid cells, only needs the information of nodes, thus makes the preceding disposal simpler. This paper reviews the generation and category of gridless method, introduces its application in solid mechanics and material mechanics, and gives expectation in its application in fluid mechanics.
Keywords: gridless method solid mechanics fluid mechanics
