    Aeronautical and automotive companies face challenges to simulate complex assembly structures (typically thousands of components), where the pre-processing of these large CAD assemblies or Digital Mock-Ups (DMUs) to convert them into FEA/CFD models is extremely time-consuming and requires highly-skilled engineers [1-2]. In practice, the initial 3D Solid models are limited to a set of individual component B-REP geometries. Consequently, analysts spend considerable time cleaning-up and defining the physical domains and their interfaces with adjacent components. To speed-up the pre-processing tasks, “simulation intent”[4] aims to structure the design space, by subdividing it into a cellular model containing both structural and void cells (air, gas, etc.), in order to create a fit-for-purpose analysis representation. In addition, it has been shown in [5] that the initial DMU can be enriched with information on interfaces between components and their functional designation to derive automatically a FEM representation of repetitive components such as fastener junctions [2]. The purpose of this paper is to describe how the enrichment and organization of CAD assembly models speed up FE model preparation for large assembly structures. The present work falls into the scope of the Marie-Curie Individual Fellowship action, MUMPS [3].
