A meshless method for the nonlinear generalized regularized long wave equation

Chinese Physics B, 2011
This paper presents a meshless method for the nonlinear generalized regularized long wave (GRLW) equation based on the moving least-squares approximation. The nonlinear discrete scheme of the GRLW equation is obtained and is solved using the iteration method.

Analysis of cutoff wavelength of elliptical waveguide by regularized meshless method

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2012
SUMMARYIn this paper, the regularized meshless method (RMM) combined with the determinant rule is taken to analyze the cutoff wavelength of elliptical waveguide with arbitrary eccentricity. First, an improved desingularization technique of subtracting and adding back is introduced for RMM to discretize this problem.

Acoustic tomography of two dimensional velocity field by using meshless radial basis function and modified Tikhonov regularization method

Measurement, 2021
Abstract A meshless radial basis function (RBF) method combined with the modified Tikhonov regularization is proposed to reconstruct the two-dimensional velocity field. Time-of-flight data is obtained to capture the flow information of the region of interest. Three kinds of RBFs are employed to acquire the coefficient matrix of the AT.

Fast-multipole accelerated regularized meshless method for large-scale isotropic heat conduction problems

International Journal of Heat and Mass Transfer, 2016
The regularized meshless method (RMM) belongs to the family of meshless boundary collocation methods and can be viewed as one kind of modified method of fundamental solutions (MFS). This method circumvents the fictitious boundary issue associated with the traditional MFS while remaining the merits of the later of being truly meshless, integration-free,

A Meshless Regularization Method for a Two-Dimensional Two-Phase Linear Inverse Stefan Problem

Advances in Applied Mathematics and Mechanics, 2013
AbstractIn this paper, a meshless regularization method of fundamental solutions is proposed for a two-dimensional, two-phase linear inverse Stefan problem. The numerical implementation and analysis are challenging since one needs to handle composite materials in higher dimensions. Furthermore, the inverse Stefan problem is ill-posed since small errors
