Optimised meshless method for acoustics
1999Summary: An element-free Galerkin method is formulated for Helmholtz problem. It is based on a moving least squares method. We show that it is possible to determine the speed of propagation of numerical wave and to tune the parameters of the method in order to minimize the dispersion.

Quadrature for meshless methods
International Journal for Numerical Methods in Engineering, 2008AbstractIn this paper we discuss quadrature schemes for meshless methods. We consider the Neumann problem and derive an estimate for the energy norm error between the exact solution, u, and the quadrature approximate solution, u, in terms of a parameter, h, associated with the family of approximation spaces, and quantities η, τ, and ε that measure the ...

MESHLESS FINITE VOLUME METHOD WITH SMOOTHING
International Journal of Computational Methods, 2014Starting from the integral forms of the equilibrium condition and the constitutive law over the small volumes centered at the nodes, this study approximates stresses and displacements independently by means of the meshless approximation. By interpreting the meshless approximation from a new perspective, the procedure does not need to differentiate the ...

Meshless Methods in Potential Inverse Electrocardiography
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006Potential inverse electrocardiography (PIE) is a method for reconstruction of epicardial potentials from measured body surface electrocardiograms and heart-torso geometry. The method of choice for computing epicardial potentials has been either the boundary element method (BEM) or the finite element method (FEM).

Topological aspects of meshless methods and nodal ordering for meshless discretizations
International Journal for Numerical Methods in Engineering, 2001AbstractThe meshless element‐free Galerkin method (EFGM) is considered and compared to the finite‐element method (FEM). In particular, topological aspects of meshless methods as the nodal connectivity and invertibility of matrices are studied and compared to those of the FE method.

In order to improve their applicability as a tool for solving partial differential equations in computational science, we equip kernel-based meshless methods with a number of new capabilities. First, we provide kernel-based meshless methods with the first wellposed, general technique which allows for adaptively-scaled trial functions.

New concepts in meshless methods
International Journal for Numerical Methods in Engineering, 2000Summary: Two kinds of truly meshless methods, the meshless local boundary integral equation (MLBIE) method and the meshless local Petrov-Galerkin (MLPG) approach, are presented and discussed. Both methods use the moving least-squares approximation to interpolate the solution variables, while the MLBIE method uses a local boundary integral equation ...
