A modified version of regularized meshless method for three dimensional potential problem [PDF]

ITM Web of Conferences, 2017
In this study, three-dimensional potential problem is solved using a novel meshless method. Due to the singularity of the kernel functions, the diagonal terms of the influence matrices in the method of fundamental solutions (MFS) are unobtainable.

Cutoff wavenumber analysis of arbitrarily shaped waveguides using regularized method of fundamental solutions with excitation sources

Electronics Letters, 2023
The method of fundamental solutions with excitation source (MFS‐ES) is a reliable method for determining the eigenvalues of a two‐dimensional hollow waveguide. However, the accuracy in MFS‐ES is extremely dependent on the choice of the auxiliary boundary.

Regularized meshless method for antiplane piezoelectricity problems with multiple inclusions

Computers, Materials & Continua, 2009
In this paper, solving antiplane piezoelectricity problems with multiple inclusions are attended by using the regularized meshless method (RMM). This is made possible that the troublesome singularity in the MFS disappears by employing the subtracting and adding-back techniques.

An investigation on the regularized meshless method for irregular domain problems

Computer Modeling in Engineering & Sciences, 2009
The regularized meshless method (RMM) is a novel boundary-type meshless method but by now has mainly been tested successfully to the regular domain problems in reports. This note makes a further investigation on its solution of irregular domain problems. We find that the method fails to produce satisfactory results for some benchmark problems.

Regularized Meshless Method for Solving Acoustic Eigenproblem with Multiply-Connected Domain

Computer Modeling in Engineering & Sciences, 2006
In this paper, we employ the regularized meshless method (RMM) to search for eigenfrequency of two-dimension acoustics with multiply-connected domain. The solution is represented by using the double layer potentials. The source points can be located on the physical boundary not alike method of fundamental solutions (MFS) after using the proposed ...

Boundary Layer Effect in Regularized Meshless Methodfor Laplace Equation

Computer Modeling in Engineering & Sciences, 2014
This paper presents an efficient strategy for the accurate evaluation of near-boundary solutions in the regularized meshless method (RMM), also known as the boundary layer effect associated with the boundary element method. The RMM uses the double layer potentials as its interpolation basis function.
