A finite element mesh generation for complex geometry

Abstract

A new approach to generate quadrilateral and pentagonal finite element meshes in convex, non convex and curved domain is presented. The method is based partially on triangle and pentagon, centroid of each triangle is considered joining the sides of its midpoints and discretised into quadrilaterals and pentagons. This procedure is applied to each triangle in the domain and a quadrilateral and pentagonal mesh is generated. For this a program has been developed in computer algebra and symbolic computational software MAPLE.
