On the Numerical Dispersion of the Radial Point Interpolation Meshless Method

IEEE Microwave and Wireless Components Letters, 2014
The numerical dispersion of the time-domain radial point interpolation meshless (RPIM) method is investigated in this letter. It is found that numerical dispersion relationship of RPIM method shares the same form as that of a second-order central finite-difference time-domain method but with the additional factor introduced by the radial basis ...

Fracture propagation using the radial point interpolation method

Fatigue & Fracture of Engineering Materials & Structures, 2019
AbstractThis work presents a crack path prediction algorithm combined with the radial point interpolation method (RPIM), a meshless method. To allow easier implementation in existing structural analysis software, this algorithm is numerically compatible with finite element method (FEM) formulations.

A Stochastic Radial Point Interpolation Method for Wideband Uncertainty Analysis

IEEE Antennas and Wireless Propagation Letters, 2021
In this letter, a time-domain stochastic radial point interpolation method (SRPIM) is developed for uncertainty quantification of electromagnetic systems. Derivatives of field quantities in Maxwell’s equations are obtained using radial basis function, and stochasticity in the dielectric constant of a part of the model space is incorporated into this ...

First- and second-order meshless radial point interpolation methods in electromagnetics

2014 1st Australian Microwave Symposium (AMS), 2014
This paper compares two different approaches for the time-domain meshless Radial Point Interpolation Method (RPIM) in electromagnetic simulations. These two algorithms are classified based on the order of partial differential equations which are needed for solving EM problems.

The local radial point interpolation meshless method for solving Maxwell equations

Engineering with Computers, 2017
The Maxwell equations are basic equations of electromagnetic. In this paper we employed ADI–LRPIM (alternative direction implicit method is applied for approximating the time variable and the local radial point interpolation meshless method is used for space variable) to solve the two-dimensional time dependent Maxwell equations.

Parallel algorithm for meshfree radial point interpolation method on graphics hardware

Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation, 2010
This study provides a parallel algorithm for meshfree analysis based on the radial point interpolation method. This algorithm is designed to suit graphics hardware that support compute unified device architecture, NVIDIA's software development environment on graphics processing units (GPUs).
