An improvement for coupled EFGM-RPIM method

Journal of the Chinese Institute of Engineers, Transactions of the Chinese Institute of Engineers,Series A/Chung-kuo Kung Ch'eng Hsuch K'an, 2016
AbstractDue to the lack of an approximation of the Kronecker-delta property, using the element-free Galerkin method (EFGM) it is difficult to impose the essential boundary condition. Coupling EFGM with the radial point interpolation method (RPIM) is a promising method.

Study of Eddy Current Analysis by a Meshless Method Using RPIM

IEEE Transactions on Magnetics, 2015
In this paper, a unique meshless method using the radial point interpolation method (RPIM) for the analysis of electromagnetic fields is proposed. In electromagnetic field analysis, treatment of the interfaces between different mediums is important.

Investigation of RPIM Shape Parameter Effects on the Solution Accuracy of 2D Elastoplastic Problems

International Journal for Computational Methods in Engineering Science and Mechanics, 2013
The effects of radial point interpolation method (RPIM) shape parameters on the solution accuracy of 2D elastoplastic problems are investigated. The RPIM algorithm is adapted for the solution of 2D elastoplastic problems using the multi-quadric radial basis function.

New treatment of essential boundary conditions in EFG method by coupling with RPIM

Acta Mechanica Solida Sinica, 2013
One of major difficulties in the implementation of meshfree methods using the moving least square (MLS) approximation, such as element-free Galerkin method (EFG), is the imposition of essential boundary conditions as the approximations do not pass through the nodal parameter values.

Coupling of NURBS and Meshfree RPIM for plane stress of web with openings

Engineering Analysis with Boundary Elements, 2022
This study presents a novel approach for the coupling of the non-uniform rational B-spline (NURBS) with the radial basis functions (RBF) under the framework of the meshfree radial point interpolation method (RPIM). In this method, denoted as N-RPIM, the NURBS basis functions are employed to model the geometry of the problem domain exactly, whilst the ...

Study of A RPIM Method Independent of Shape Parameters

2020 IEEE MTT-S International Conference on Numerical Electromagnetic and Multiphysics Modeling and Optimization (NEMO), 2020
Generally, the value of a shape parameter will affect the accuracy of the radial point interpolation method (RPIM). However, a small shape parameter will cause this meshless method become unstable. In this paper, we expand the Gaussian basis function with a polynomial.

Adaptive RPIM meshless method

2011 International Conference on Multimedia Technology, 2011
Combining a kind of new adaptive technique with the radial point interpolation method (RPIM), it yields the adaptive RPIM meshless methods. We solved the classical cantilever beam problem using this method. Numerical results show the accuracy and efficiency of the present method.

RPIM-SM: extending PIM-SM for RP relocation

Computer Communications, 2002
The protocol independent multicast-sparse mode (PIM-SM) protocol establishes core-base tree to forward multicast datagrams in a network. In PIM-SM, the core or rendezvous point (RP) of a group is determined at each multicast router by hashing a group address, i.e. a class-D IP address, to one of the candidate RPs.

RPIM: Inferring BGP Routing Policies in ISP Networks

2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011
BGP dictates routing between autonomous systems with rich policy mechanisms in today's Internet. Operators translate high-level policy objectives into low-level router configurations without a comprehensive understanding of the actual effects on the network behavior, leaving the routing management an error-prone and time-consuming procedure.

Solution of Material Mechanics by RPIM Meshless Method

Advanced Materials Research, 2013
With the compact support of radial point interpolation shape functions (RPIM), the stiffness matrix of system equation can be sparse, so its very suitable for meshless methods.This interpolation method have the Kronecker delta function property, so the essential boundary conditions can be enforced directly and accurately without any additional ...
