A NEW 'FLOATING NODES METHOD' FOR 2D h-ADAPTIVE MESH REFINEMENT USING ELECTRIC FIELD INTENSITY VALUES AS A CRITERION

Abstract

Suitable fine mesh divisions are essential to obtain fast and accurate solutions in two- dimensional electric field analysis. However, the development of such fine division meshes always requires considerable technical knowledge and experience. A way of solution wbich proves highly effective is the application of adaptive methods for refinement of the division meshes. Since the researchers in the analysis of various electric field problems are usually interested in the values of electric field intensity and its distributions, it seems natural to employ these values as a criterion for mesh refinement. In this paper, we propose an h-adaptive refinement procedure by generating new nodes inside initial rough mesh. Also, we propose the improvement of the shape of finite elements by using a 'floating nodes method'. For both procedures, electric field intensity values were used as criteria.
