• In this paper, the nodal placement of radial point interpolation meshless technique for finite difference time domain method is investigated. The first widely applied placement is a manner similar to the point-matched time-domain finite-element method, which is convenient for the regular node distribution. Another one is the Voronoi decomposition which is applied to nonuniform distribution. The point-matched method does not take full advantages of adaptive characteristic of meshless method for complex problems. While the Voronoi decomposition is time consuming for 3-D case and may suffer from the matrix singularity of the associated polynomial basis function. An alternative solution is discussed by utilizing hybrid application of the above two methods.
