摘要
无网格法是一种新兴的数值计算方法,具有独特的性质。简述了无网格法的理论基础及其所具有的优势,详细介绍了几种常用的无网格算法,并以移动最小二乘近似法为重点,对无网格法中的形函数构造作了详细论述。最后,分析了无网格法在小尺度封闭空间声场数值计算中的应用。
Meshless method is a kind of numerical approach which is developed in recent years.It has more special and excellent characteristics than the finite element method.In this paper,its basic principle and advan-tages are introduced.Some main meshless methods are introduced in detail.The constitution approaches of the shape function are analyzed with taking the moving least-square method as a key point.Finally,its applications in calculation of the sound field in small enclosure are discussed.
