Numerical Investigation on Direct MLPG for2D and 3D Potential Problems
Computer Modeling in Engineering & Sciences, 2012 Pure meshless techniques are promising methods for solving Partial Differential Equations (PDE). They alleviate difficulties both in designing discretization meshes, and in refining/coarsening, a task which is demanded e.g. in adaptive strategies.

Application of the MLPG to Thermo-Piezoelectricity
Computer Modeling in Engineering & Sciences, 2007 A meshless method based on the local Petrov-Galerkin approach is proposed for the solution of boundary value problems for coupled thermo-electro-mechanical fields. Transient dynamic governing equations are considered here. To eliminate the time-dependence in these equations, the Laplace-transform technique is applied.

Elastic transient analysis with MLPG(LBIE) method and local RBFs
Computer Modeling in Engineering & Sciences, 2009 A Meshless Local Petrov-Galerkin (MLPG) method based on Local Boundary Integral Equation (LBIE) techniques is employed here for the solution of transient elastic problems with damping. The Radial Basis Functions (RBF) interpolation scheme is exploited for the meshless representation of displacements throughout the computational domain.

An Efficient Parallel MLPG Method for Poroelastic Models
Computer Modeling in Engineering & Sciences, 2009 A meshless model, based on the Meshless Local Petrov-Galerkin (MLPG) approach, is developed and implemented in parallel for the solution of axi-symmetric poroelastic problems. The parallel code is based on a concurrent construction of the stiffness matrix by the processors and on a parallel preconditioned iterative method of Krylov type for the ...

A new Singular/Hypersingular MLPG (LBIE) method for 2D elastostatics
Computer Modeling in Engineering & Sciences, 2005 A new meshless local Petrov-Galerkin (MLPG) type method based on local boundary integral equation (LBIE) considerations is proposed for the solution of elastostatic problems. It is called singular/hypersingular MLPG (LBIE) method since the representation of the displacement field at the internal points of the considered structure is accomplished with ...
