The MLPG for modeling of flexoelectricity
AIP Conference Proceedings, 2019The meshless Petrov-Galerkin (MLPG) method is developed to analyse general boundary value problems where the electric field and displacement gradients exhibit a size effect. Both the electric intensity vector and strain gradients are considered in the constitutive equations for piezoelectric material.

Phase Change Problems Using the MLPG Method
Numerical Heat Transfer, Part A: Applications, 2011This article discusses the application of the MLPG method to phase change problems. Phase change problems belong to a nonlinear class of problem due to a continuously moving interface. Apparent capacity method based on the enthalpy formulation is used here.

MLPG/SUPG Method for Convection-Dominated Problems
Numerical Heat Transfer, Part B: Fundamentals, 2012It is well known that convection-diffusion equations suffer from the most difficult problems to gain a stable and accurate solution. Sometimes, the convection terms may cause oscillatory behavior of solutions. In this article, the streamline upwind Petrov-Galerkin (SUPG) scheme is applied to eliminate overshoots and undershoots produced by the ...

An Efficient Hybrid Implementation of MLPG Method
Journal of Multiscale Modelling, 2017The computational implementation of moving least squares (MLS) shape functions is an important step to consider in some versions of the meshless local Petrov–Galerkin (MLPG) method for a variety of two-dimensional engineering problems. Here, the usage of conventional Gaussian quadrature in the MLPG may require an excessive number integration points to

MLPG method for convection-dominated flow problems
Progress in Computational Fluid Dynamics, An International Journal, 2012In this paper, the Meshless Local Petrov-Galerkin (MLPG) method is applied to compute convection-dominated flow problems. The results of the MLPG method are compared with the results of the finite volume method. The results show that the first-order upwind (FUD) scheme exhibits the false diffusion at a larger-Peclet number; the QUICK scheme and the ...

Analysis of errors in MLPG methods
AIP Conference Proceedings, 2012The locality of meshless methods for the numerical solution of partial differential equations is achieved by the moving least squares (MLS) approximation. We analyzed experimentally the errors in the MLS approximation and in the meshless local Petrov-Galerkin (MLPG) solution method and confirmed that there is only a short interval of MLS support radii ...
