Application of Meshless Local Petrov-Galerkin (MLPG) Method in Cloth Simulation
Computer Modeling in Engineering & Sciences, 2008 In this paper we present an approach to cloth simulation which models the deformation based on continuum mechanics and discretized with Meshless Local Petrov-Galerkin (MLPG) Method. MLPG method, which involves not only a meshless interpolation for trial functions, but also a meshless integration of the local weak form, has been considered as a general ...

Meshless Local Petrov-Galerkin (MLPG) Method for Convection-Diffusion Problems
Computer Modeling in Engineering & Sciences, 2000 Due to the very general nature of the Meshless Local Petrov-Galerkin (MLPG) method, it is very easy and natural to introduce the upwinding concept (even in multi-dimensional cases) in the MLPG method, in order to deal with convection-dominated flows. In this paper, several upwinding schemes are proposed, and applied to solve steady convection-diffusion

Multiscale Simulation Based on The Meshless Local Petrov-Galerkin (MLPG) Method
Computer Modeling in Engineering & Sciences, 2004 A multiscale simulation technique based on the MLPG methods, and finite deformation mechanics, is developed, implemented, and tested. Several alternate time-dependent interfacial conditions, between the atomistic and continuum regions, are systematically studied, for the seamless multiscale simulation, by decomposing the displacement of atoms in the ...

Meshless Local Petrov-Galerkin (MLPG) Mixed Finite Difference Method for Solid Mechanics
Computer Modeling in Engineering & Sciences, 2006 The Finite Difference Method (FDM), within the framework of the Meshless Local Petrov-Galerkin (MLPG) approach, is proposed in this paper for solving solid mechanics problems. A "mixed'' interpolation scheme is adopted in the present implementation: the displacements, displacement gradients, and stresses are interpolated independently using identical ...

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019 The paper analyzed the thermal problem of the 2D FGM beam using meshless weighted least‐square (MWLS) method. The MWLS as a meshless method is fully independent of mesh, and an approximate function was used to construct a series of linear equations to solve the unknown field variable, which avoided the troublesome task of numerical integration.

Meshless local Petrov-Galerkin (MLPG) method in combination with finite element and boundary element approaches [PDF]
Computational Mechanics, 2000 Combinations of the meshless local Petrov-Galerkin (MLPG) method with finite element (FE) and boundary element (BE) methods are proposed for elasticity boundary value problems with the aim to improve the solution efficiency. Special interface elements are needed along the border of MLPG and FE (or BE) regions in order to satisfy the displacement ...

Meshless Singular Boundary Method for Nonlinear Sine‐Gordon Equation
Mathematical Problems in Engineering, Volume 2018, Issue 1, 2018., 2018 A meshless method based on the singular boundary method is developed for the numerical solution of the time‐dependent nonlinear sine‐Gordon equation with Neumann boundary condition. In this method, by using a time discrete scheme to approximate the time derivatives, the time‐dependent nonlinear problem is transformed into a sequence of time‐independent
