5 Finite Element Method Brief Presentation

5.1 INTRODUCTION

The evolution of the FEM is intimately linked to developments in engineering and computer sciences. Its application in a variety of areas, especially in the nuclear, aeronautics, and transportation industries, is a testimony to the high degree of accuracy the method is capable of, as well as to its ability to model complex problems. There are different ways to define, present, and use FEM. Our choice here is based on our implementation experience on which we adopted the approaches using the FE real coordinates as well as the concept of”reference element We intend to present, in a relatively direct and short manner, the FEM by using very classical algebra, and it is not our intention ...
