Flexible mesh generator for triangular and quadrilateral areas

The object of this paper is to propose a new method to generate the topological properties among the input data necessary for the user of the Finite Element Method. The method can generate the element-node relation for triangular and quadrilateral areas which are required to subdivide into different numbers of segments on their edges. This flexibility can largely remove the complexity of the mesh generation of two-dimensional area. The algorithm of the proposed method is so simple as to be used on a microcomputer. The main part of program listing written in BASIC is attached to this paper.
