Analyzing Engineering Simulations in a Virtual Environment
November-December 1998 (vol. 18 no. 6)
pp. 46-52
The use of virtual prototypes generated from engineering simulations can be crucial to the efficient development of innovative products. Performance predictions and functional evaluations of a design are possible long before results of real prototype tests become available. This article presents new results of ongoing research at the University of Erlangen and at BMW in developing a virtual environment for car-body engineering applications. They extend to a variety of different fields such as structural mechanics, aerodynamics, acoustics, and air conditioning, to name just a few. In each of these fields, the task at hand is twofold: first, to predict the physical behavior of a complex technical system; second, to use the analysis results to effectively introduce the necessary engineering changes. Creating VRML scenes makes it possible to use intranets or the Internet as a communication platform.
