10.7.1 Introduction

Due to tremendous development of FEM in various areas of Engineering and Sciences for the past 50 years or so, a large number of software and packages are available commercially and also as open sources. Even though few packages can solve problems in more than one area, most FEM packages are area specific and can solve only particular set of problems. Furthermore, while few packages can be employed to solve problems in three-, two- and one-dimensional domains, many packages can be employed to solve problems in one- or two-dimensional domains. Most of earlier packages did not have any graphical user interface (GUI) for discretization and data preparation and, thus, the pre- and post-processing ...
