“…The Application Protocol 209 (AP209), created in 2001, improves design analysis and manufacturing productivity of composites and metallic structures. It provides a data model to share CAE data during the whole product lifecycle [22]. This standard involves a neutral file format to avoid interoperability problems between different systems and, thus, to drastically reduce analysis costs.…”

-Recent evolutions of computer-aided product development and massive integration of numerical simulations to the design process require new methodologies to manage the continuously increasing flow of data and decrease the computational costs of numerical design of experiments. This paper presents a literature review of Simulation Data Management strategy and adaptive design of experiments methodology to detect possible links between these two fields and identify potential improvements for simulation process shortening. Adaptive design of experiments is based on several methods implying a profusion of different technics. Re-using best practices may help designers to choose relevant methods to reduce computational cost and simulation process duration.

“…Unfortunately, there is a huge difference between the STEP standard itself and the way it is implemented in commercial CAD/FEA systems, if it is. Consequently, data transfer between various commercial CAD/FEA systems through STEP in a unique and universal format is not practically efficient, even if it can be used quite successfully for specific needs [5]. Beall [2] presents the three solutions mentioned above and illustrates them with specific examples.…”

We have been involved in research work in the field of finite element analysis (FEA) integration with computer aided design (CAD) for several years and have developed several concepts and tools that have aroused interest and shown efficiency. In the meantime, both the evolution of our research developments (on topics like geometry comparison, geometry reconstruction and simplification, mixed-dimensional analysis and topology optimization) and the evolution of CAD systems and CAD kernels made us reconsider our database organization. This led to the design of an original development environment and database organization referred to as the Unified Topological Model (UTM). The main interests of this new CAD/FEA database organization is its ability to tackle multi-platform CAD/FEA integration (handling geometries coming from different CAD kernels), mixed-dimensional modeling and analysis (3D solid geometry mixed and integrated with surface geometry and curvilinear geometry) and topology optimization (TO) procedures. The paper presents the structure of this new research development environment and the original concepts underlying it. The UTM environment is strongly designed around object-oriented computer programming concepts and it is focused towards generality, modularity and ability to evolve. The paper also briefly presents some of the most important features and algorithms that have been integrated, at this point, into the UTM environment.
