| 摘 要： | 0引言 Helmholtz方程作为简化的波动方程,长期以来备受关注.求解Helmholtz方程的数值方法主要有有限差分法、有限元法和边界元法等.这些方法主要基于网格近似或者需要背景网格积分,在处理高波数或高频率Helmholtz方程及高维问题时存在网格划分困难和内存消耗大等缺点.基于点的近似思想,无网格方法在一定程度上减少对网格的依赖,甚至不需要网格。

| Abstract: | In this paper, applications of boundary knot method to solve the acoustic problems are presented at first. For the merits proposed by the boundary knot method, a MATLAB toolbox is developed for researchers to solve some engineering problems. It should be noted that regularization techniques are absorbed in this toolbox. This toolbox maintains the advantages that simply to use, high accuracy, ability to solve complex problems. |
