The Natural Neighbour Petrov-Galerkin Method

摘要:<正> In most meshless methods, special techniques are needed for the imposition of essential boundary condition because the shape functions lack the Kronecker Delta function property, which result in the decrease of the accuracy and increase of the computing cost. In order to solve this problem, the natural neighbour Petrov-Galerkin method (NNPG) is proposed based on the combination of the non-Sibsonian interpolation with Petrov-Galerkin procedure. This method is an efficient truly meshless method, and it is able to impose the essential boundary condition directly.
