Programming Finite Elements In Javatm

The finite element method (FEM) is a computational technique for solving problems which are described by partial differential equations or which can be formulated as functional minimization. The FEM is commonly used in the design and development of products, especially where structural analysis is involved. The simple object model of the Java(TM) programming language lends itself to efficient implementation of FEM analysis. Programming Finite Elements in Java(TM) teaches the reader FEM algorithms and their programming in Java(TM) through a single finite element Java(TM) program. The compact, simple code makes it straightforward to understand the algorithms and their implementation, thereby encouraging developers to extend the code to their own tasks. All of the main aspects of finite element techniques are considered: finite element solution; generation of finite element meshes; and visualization of finite element models and results with Java 3D(TM). The step-by-step presentation includes algorithm programming and code explanation at each point. Problems and exercises are provided for each chapter, with Java(TM) source code and problem data sets available from http://extras.springer.com/2010/978-1-84882-971-8. Graduate students using the FEM will find the simple but detailed object-oriented programming methods presented in this textbook to be of great assistance in understanding the FEM, including mesh generation and visualization. Programming Finite Elements in Java(TM) will also be of interest to senior undergraduates doing special studies encompassing the FEM. Researchers and practicing engineers already familiar with the FEM but seeking an alternative approach will find this book readily suited to self study.

This book provides an introduction to programming the finite element method in Java for students, researchers and engineers who are reasonably familiar with the finite element method and want to learn how to write their own finite element code using Java. This book is written as an introductory text and it is assumed that the reader has little or no knowledge of object-oriented programming or Java. By concentrating on line elements, specifically structural trusses, it is possible to make the code very simple and relatively easy to understand. The philosophy of the book is to teach the reader how to write a very simple object-oriented finite element code in Java, with the understanding that once the reader has these skills they should easily be able to extend the code to more complex problems. As newcomers to programming find dealing with command line executed software frustrating and challenging; the Android operating system is used to develop a graphical user interface to allow the reader to interact with their Java code. Android provides a relatively simple (and very well supported) platform for coding a user interface and means that the finished application will work on any Android device (smartphone, tablet, etc.) The book is supported by a webpage which contains the source code for the Android app and other helpful material. The Android app that is detailed in the book is also available for download from the Google Play store.

Programming Finite Elements in JavaTM teaches the reader how to programme the algorithms of the finite element method (FEM) in JavaTM. The compact, simple code helps the student to read the algorithms, to understand them and thus to be able to refine them. All of the main aspects of finite element techniques are considered: finite element solution; generation of finite element meshes; and visualization of finite element models and results with Java 3DTM. The step-by-step presentation includes algorithm programming and code explanation at each point. Problems and exercises are provided for each chapter, with JavaTM source code and problem data sets available from http://extras.springer.com/2010/978-1-84882-971-8.

This title demonstrates how to develop computer programmes which solve specific engineering problems using the finite element method. It enables students, scientists and engineers to assemble their own computer programmes to produce numerical results to solve these problems. The first three editions of Programming the Finite Element Method established themselves as an authority in this area. This fully revised 4th edition includes completely rewritten programmes with a unique description and list of parallel versions of programmes in Fortran 90. The Fortran programmes and subroutines described in the text will be made available on the Internet via anonymous ftp, further adding to the value of this title.

This text provides the reader with a unique insight into the finite element method, along with symbolic programing that fundamentally changes the way applications can be developed. It is an essential tool for undergraduate or early postgraduate courses as well as an excellent reference book for engineers and scientists who want to quickly develop finite-element programs. The use of symbolic computation in Maple system delivers new benefits in the analysis and understanding of the finite element method.

The book introduces the finite element method (FEM) that is one of the most powerful numerical tools these days. FEM is the analysis tool in most of CAD/CAM systems and it is critical to understand FEM for engineering design. It begins with underlying variational calculus and moves to variational/FEM formulations. It covers all basic procedures of assembly and solution procedures in several programming practices. Finally, it introduecs Ansys and Ansys WB software to apply FEM to advanced topics in various areas of engineering.

Market_Desc: Engineers Special Features: · Matrix notation is used for the development of all finite element equations. This allows reader to visualize the matrix equations as they are used and manipulated in finite element codes.· The exercises at the end of each chapter are divided into three categories; study problems, numerical experiments and code development, and projects. About The Book: This text presents an introduction to the finite element method including theory, coding, and applications. The theory is presented without recourse to any specific discipline, and the applications span a broad range of engineering problems. The codes are written in MATLAB script in such a way that they are easily translated to other computer languages such as FORTRAN. All codes given in the text are available for downloading from the book's Web page, along with data files for running the test problems shown in the book.
