網際網路已改變了傳統系統程式的使用方式，許多大型軟體系統均已朝向網路化發展，例如電子商務或搜尋引擎背後的應用程式與大型資料庫的搜尋，乃至於工程計算的分析服務，均已經與網際網路結合，可讓許多使用者於遠端，使用簡單的上網設備，通常只需使用一般的PC與瀏覽器，即可同時連線使用執行於伺服端上的軟體系統。
以往的網路式分析服務皆有兩項缺乏或不完整功能要素，分別是用戶端3D使用者介面與伺服端高速計算環境，本論文之研究目的即是整合Web-3D開發出Java-based Web 3D 為基礎的有限元素分析系統用戶端3D使用者介面。使用者只需一部連接上網路的電腦，便可以使用遠端的系統與高速計算平台所提供的有限元素分析服務，從事結構分析工作。並且透過Web-3D界面，使使用者更能輕易進行分析工作以及檢視分析結果。另一個目為以XML為系統間檔案之格式，透過XML宜於轉換及交換的特性，可整合其他伺服端有限元素分析系統用戶端的前處理與後處理程式，讓檔案不只限於在本系統提供之Web-based介面上使用，也能相容於其他分析程式的使用者介面，使設計工作更加彈性，系統功能更加提昇。

This paper presents a new Internet-based finite-element analysis framework, named Web-FEM, which allows users to access finite-element analysis service at remote sites over the Internet by using an Internet-connected machine only. The implementation utilizes modern computer graphics, parallel processing, and information technology to provide features such as platform-independence, 3D graphical interface, system performance, multiple-user management, and fault tolerance in comparison with other Internet-based analytical systems. These features make its usage like using a traditional finite element package installed and run on a local machine, and its performance like using a high performance computing facility. The system architecture consists of three components. The only component on the client computer is a Java program, which handles the presenting of data and interacting with the user. One component on the server machine is a parallel C++ program, which handles core computation. Another component on the server machine is a Java program, which coordinates the previous two components over the Internet to integrate them to work as a single system. The object model design and the implementation of this three-tier system are presented in detail.
