Efficient cubature formulae for MLPG and related methods

International Journal for Numerical Methods in Engineering, 2005
AbstractThe paper introduces four kinds of compact, simple to implement Gaussian cubature formulae for approximating the domain integrals arising in the discrete local weak form (DLWF) of a governing partial differential equation solved by means of the meshless local Petrov–Galerkin method of type MLPG1.

The Galerkin least squares MLPG method for convection-dominated problems

Progress in Computational Fluid Dynamics, An International Journal, 2021
The meshless method has been widely applied in the computational mechanics, materials science, computational heat transfer and fluid flow. However, the development of a high efficient method for convection term in the computational fluid dynamics is difficult.

Analysis of rubber‐like materials using meshless local Petrov–Galerkin (MLPG) method

Communications in Numerical Methods in Engineering, 2007
AbstractLarge deformations of rubber‐like materials are analyzed by the meshless local Petrov–Galerkin (MLPG) method. The method does not require shadow elements or a background mesh and therefore avoids mesh distortion difficulties in large deformation problems.

A new coupled MLPG-FE method for electromagnetic field computations

Proceedings. ICCEA 2004. 2004 3rd International Conference on Computational Electromagnetics and Its Applications, 2004., 2005
Considering an analysis of advantages and disadvantages of existing coupled finite element (FE) and meshless methods (MM), a new coupled MLPG-FE (meshless local Petrov-Galerkin-FE) method is proposed and successfully applied to electromagnetic field computations.

Meshless Local Petrov-Galerkin (MLPG) Method for Incompressible Viscous Fluid Flows

Volume 2: Fora, 2006
In this paper, the truly Meshless Local Petrov-Galerkin (MLPG) method is extended for computation of unsteady incompressible flows, governed by the Navier–Stokes equations (NSE), in vorticity-stream function formulation. The present method is a truly meshless method based only on a number of randomly located nodes.

Numerical Modeling of Material Discontinuity Using Mixed MLPG Collocation Method

2015
A mixed MLPG collocation method is applied for the modeling of material discontinuity in heterogeneous materials composing of homogeneous domains. Two homogeneous isotropic materials with different linear elastic properties are considered. The solution for the entire domain is obtained by enforcing the corresponding continuity conditions along the ...

Numerical analysis of 2-D linear elastic problems by MLPG method

2012
Meshless methods have attracted considerable attention of the scientific community over the last two decades due to their flexibility and high continuity of meshless approximation functions. However, high numerical costs in comparison to the Finite Element (FE) Method still impede their wide commercial use.
