Computer-aided engineering (CAE) analysis is considered essential for product development because it decreases the simulation time, reduces the prototyping costs, and enhances the reusability of product parts. The reuse of quality-assured CAE data has been continually increasing in order to shorten the product development cycle and to improve the product quality. However, less attention has been paid to systematic research on the interoperability of CAE data because of the diversity of CAE data and because the structure of CAE data is more complex than that of CAD data. In this paper, we suggest a CAE data exchange method for the effective sharing of geometric and analysis data. The method relies on heterogeneous CAE systems, a virtual reality system, and our developed lightweight CAE middleware for CAE data exchange. We also designed a generic CAE kernel, which is a critical part of the CAE middleware. The kernel offers a way of storing analysis data from various CAE systems, and, with the aid of a script command, enabling the data to be translated for a different system. The reuse of CAE data is enhanced by the fact that the CAE middleware can be linked with a virtual reality system or a product data management system. [ABSTRACT FROM AUTHOR]

COMPUTER integrated manufacturing systems, COMPUTER software, and MACHINE design
An Integrated Machine Design and Control (IMDC) environment is described that can improve the visual representation of machines and integrate the design of each physical machine element with the design of its associated control logic. The approach overcomes many of the problems traditionally associated with the implementation of computer controlled machines, which is a process often characterized by poor verification of customer requirements, limited confidence in proposed designs, minimal software re-use and difficult system maintenance or enhancement. IMDC is a new approach to machine lifecycle support that embodies a highly integrated environment for system builders. The approach provides much needed support for rapid prototyping, 'what-if' analyses and enables machines to be incrementally enhanced. IMDC allows the integration of design and control system elements from a wide range of vendors. From a user's perspective, the two main elements of the IMDC environment are: (1) an extendible software toolset and (2) a run-time control architecture. Underlying these elements is the IMDC integration platform that provides data storage, integrates and manages the user toolset and connects these off-line system components to the run-time control architecture. The interactive use of IMDC tools is explained in the context of achieving rapid prototype machine build. Industrial applications of the IMDC approach are described. [ABSTRACT FROM AUTHOR]
