Data Management for Simulations in CAE

摘要

Analysis of the properties of complex industrial products (e.g. cars, ships, aircraft) is performed by means of digital and physical simulations. Improvements in measurement techniques, improved algorithms, and the availability of powerful computers lead to a vast amount of data to be handled and to be interpreted by engineers, within a short turn-around time. Consequently, requirements are imposed on facilities for management and usage of this vast amount of data. Not all requirements are met to a satisfactory level by the current database management technology. As a consequence specific data management solutions have to be applied in different situations, characterized by different properties of the various processes and of the internal structure of the data. The paper presents a classification of the requirements and the related data management solutions. The solution chosen at NLR is presented, which implies a data management system in which both a database manager and a standard record handler are integrated. Examples are given in the area of aircraft flow simulation.
