Research Abstract

In the present study, we successfully formulated the new scheme without mesh concept for solving a partial differential equation by dissociating the illustration of domain shape and construction of interplant functions from the Finite Node Method (FNM) and the Boundary Node Method (BNM). We investigated the possibility of applicable for the electromagnetic analysis, and the methods were achieved to applied for the problems. In addition, the new formulated scheme could permitted the imposing various boundary conditions.
