| 摘 要： | 将径向基函数无网格配点法用于求解泊松方程，此方法无需背景积分网格，是一种真正的无网格法。采用三种不同的径向基函数来求解，讨论了形参取值对求解精度的影响，收敛性也得到了证明，编制相应的计算机程序进行计算，结果精度令人满意。

| Abstract: | A meshless method based on radial basis functions is presented to solve Possion equations. This method is a truly meshless technique without mesh discretization. Different shape parameters of three kinds of radial basis functions are used to show their feasibilities to the solution, and the converge is aLso assessed. A numerical example is implemented to show the effectiveness and feasibility of the proposed method. |
