Abstract

In any analysis of practical problem using Finite Element Method (FEM), discretization errors are intentionally introduced which most of the time lead to boundary mismatch problems in curved areas where boundary condition of a third kind is applied. In this paper linear finite elements approach with a Multi-Edge concept and h-Adaptive mesh generation have been proposed to minimize the numerical errors.
