Numerical Solution of Sine‐Gordon Equation with the Local Kriging Meshless Method
Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020 This paper develops a local Kriging meshless solution to the nonlinear 2 + 1‐dimensional sine‐Gordon equation. The meshless shape function is constructed by Kriging interpolation method to have Kronecker delta function property for the two‐dimensional field function, which leads to convenient implementation of imposing essential boundary conditions ...

Further Developments in the MLPG Method for Beam Problems
Computer Modeling in Engineering & Sciences, 2003 An accurate and yet simple Meshless Local Petrov-Galerkin (MLPG) formulation for analyzing beam problems is presented. In the formulation, simple weight functions are chosen as test functions as in the conventional MLPG method. Linear test functions are also chosen, leading to a variation of the MLPG method that is computationally efficient compared to
