Modele de donnees pour la representation d'informations de simulation dans un processus d'optimisation de composantes hydrauliques (French text).

摘要

The work presented in this paper aims to define the infrastructure necessary to facilitate the data exchange between various tools of analysis and multidisciplinary optimization. The automation of the optimization process of the hydraulic turbine blades design is a complex process, which integrates several under-processes resulting from various fields. Hence, the integration of several under-processes implies data exchange between those under-processes.; A CFD data model for representation of numerical information in the specific field of the water turbines was developed. The data model was developed on the basis of the abstract concept to define and structure CFD data defined by the CGNS standard.; Studying the approaches employed by the standards in the field of CFD and CAD data representation, it is proposed a flexible approach which allows imposing constraints at the level of the structure and contents, while respecting the CGNS standard. Furthermore, a XML based method to manage the way of imposing constraints on a CFD data base, was developed. It was showed also, how this new approach can be used to bring generated by various commercial or in house tools data structures in the definite standard form. (Abstract shortened by UMI.)
