GEN2D: A Mesh Generation Program for 2D Axisymmetric Finite Element Mesh of Q-8 Elements

摘要

Although the finite element method greatly facilitates the analysis of engineering problems, the job of data preparation for a realistic problem can be very demanding. The tedious process of manual data preparation and checking can take up enormous amounts of time. So, automatic generation of a mesh is of obvious practical value in reducing the work load and the chances of human error in the process. This program is written to generate meshes of Q-8 elements with plane or curved surfaces from a minimum amount of information supplied in digital form. The program is designed in such a way that the generated mesh can: adequately describe the boundary whether it is singly or multiply connected; describe zones of different materials wherever these occur; and grade the mesh so as to achieve required accuracy of idealization.
