Abstract: The finite element (FE) analysis and design process deals with large amounts of complex engineering data. Although sophisticated techniques have been developed for computer-aided FE analysis, the FE software has lacked robust and integrated data management strategies to support persistent and concurrent analysis and design. The FE analysis and design software applications should be independent of the data management aspects catered to by database systems, which support high-level access to the analysis data and its manipulation. The interface between the applications (or designers) and the database should be supported by well-defined transactions. In this paper, we describe transactional support for integrating FE analysis and design applications with a database management system. To this end, we interpret analysis and design steps as transactions on the database objects. A prototype implementation is used for illustration.
