An Automatic Finite Element Mesh Generator

Abstract

Finite element computer codes are used in variety of fields to solve partial differential equations of importance in science and engineering. The initial input to all of these programs requires the formation of a mesh (i.e., extensive lists of geometrical data listed in particular orders), and the success of the solution depends on a well-formed mesh. This report documents a mathematical mapping technique and its implementation into a user-friendly computer code that will automatically generate quality finite element meshes. This versatile generator uses standard FORTRAN, requires no special equipment (such as a digitizer), is very economical to run, and is user-friendly. The mathematical technique is discussed, advantages and limitations of the method are presented, and notes on user instructions are provided. Keywords: Computer code; Differential equations; Finite element; Fluid dynamics; Heat transfer; Mathematical methods; Solid mechanics.
