Summary

The Application Service Providers (ASP) have deserved attention of the main hardware and software companies. The ASP aim to make applications and hardware resources available from an Internet connection. The initial applications available for ASPs were relatively simple but have increased in terms of memory and CPU requirements and network bandwidth.

From the user perspective, the main advantages of the ASP concept are the automatic update and access to the most recent version of the applications, access to applications and files everywhere and payment based on the effective used resources. This last feature means that software becomes a service instead of a product which is bought and maintained by companies. The disadvantages are related to the Internet security and low bandwidth for intensive applications.

In general, engineering applications are memory and CPU intensive and require interaction and visualization resources. Based on the current technological stage of the commercial Internet, the use of the common engineering software in browsers are not possible. However, many simple applications may be implemented and used in the Internet connection.

This work presents a mesh generation software applied to the Finite Element Method with a web-based version. From a HTML form, users supply the geometric model filename and the mesh attributes Based on this information, a PHP program interprets data and writes an input command file to the mesh generation software which is based on the MeshSim kernel. Another PHP program monitors the mesh generation process. After finishing, it sends an e-mail to the user with the status of the mesh generation process. If it has been sucessful, output files are available for download and a VRML file may be open in Internet browsers to visualize the mesh.
