Imposing boundary conditions in the meshless local Petrov–Galerkin method
IET Science, Measurement & Technology, 2008 A particular meshless method, named meshless local Petrov-Galerkin is investigated. To treat the essential boundary condition problem, an alternative approach is proposed. The basic idea is to merge the best features of two different methods of shape function generation: the moving least squares (MLS) and the radial basis functions with polynomial ...

Meshless Local Petrov-Galerkin (MLPG) Method for Convection-Diffusion Problems [PDF]
, 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.

Meshless Local Petrov-Galerkin Method in Anisotropic Elasticity
Computer Modeling in Engineering & Sciences, 2004 A meshless method based on the local Petrov-Galerkin approach is proposed for solution of static and elastodynamic problems in a homogeneous anisotropic medium. The Heaviside step function is used as the test functions in the local weak form. It is leading to derive local boundary integral equations (LBIEs).
