Summary
Since the time numerical simulation tools have been introduced in design engineering the requirements on their capabilities have increased steadily. Computer resources and people's expectations on the simulation itself have reached a high level over the years. More powerful computers are used to process meshes with several million cells. 3-d time accurate calculations with moving or deforming meshes are manageable as well as large eddy and direct numerical simulations. Advanced visualization techniques are used to extract more information leading to a deeper understanding of complex flow phenomena. Using examples of ongoing and recently finished projects the use of flow simulation methods and visualization tools will be presented. The use of commercial tools for cfd and post processing and their adaptation for simulation of human comfort as well as for particle transport simulations will be presented and potentials for topology based visualization methods will be pointed out.
