摘要
构造了Helmholtz方程具径向基函数的无网格方法.通过引入多种径向基函数构造了Galerkin型的无网格方法.文末给出了数值算例,并与有限元方法进行了比较.讨论了无网格方法的数值精度以及径向基函数中参数对其数值解的影响.结果表明具径向基函数的Galerkin型无网格方法是求解Helmholtz方程的一种有效且精度高的方法.
The meshless method with radial basis functions (RBF) for Helmholtz problem is constructed. By introducing various RBF, it yields the meshless method of Galerkin type. Finally the numerical example is given, and by comparing with FEM, it discussed the numerical precision and the effect of the parameter c in RBF to its numerical solution. The result shows that the meshless method of Galerkin type with RBF is an efficient and high precision method.
