In this paper, we present an interactive framework, which is capable of delivering access to huge amounts of data from Building Information Models (BIM) and digital terrain data by using hierarchical data structures and elaborate algorithms in an efficient multi-level fashion. This framework bridges the gap between big datasets and accurate numerical simulations by exploiting parallelisation and data distribution techniques based on the geometric information existing at various levels. By having such a framework at hand, results of numerical simulations become applicable, which take on the one hand side multi-level geometric information from a global to a fine detailed level into account, and on the other hand side can make use of auxiliary information. These auxiliary information result from the underlying product model data and give the input for simulation relevant details, such as part specific material parameters e.g. As applications of the framework, besides a scalable parallel immersive visualisation, we present the integration of a massive parallel CFD simulation following the Lattice-Boltzmann-Method, a multi-scale extension of a spatial version of the Structured-Query-Language(SQL), and the coupling to a grid generation framework.     «
