In this paper we present the recently developed application VirtualFluids for exploring three-dimensional flowfields generated by a numerical CFD simulation together with a CAD-model of a building. Our objective is to extract a detailed understanding of ow structures from the simulation data, and hence an optimization of the iterative process of communication between architects and engineers during the planning of a building. VirtualFluids uses classical techniques like isosurfaces, slicing and particle tracing to visualize the data, while it represents the building using textured surfaces. The program can be easily extended with new operators in order to extract additional features from the simulation dataset or with interfaces loading other types of simulation data (e.g. structural mechanics or thermal simulation). Special attention was given to the design of a user interface being easy to learn and to use, making VirtualFluids suitable for Virtual Reality environments. We describe the features of the application, discuss its implementation and show results obtained by VirtualFluids.     «
