Analyzing large, time-dependent, and high-dimensional data sets resulting from CFD (computational fluid dy-namics) simulations is a difficult and often very time-consuming task. Especially in the field of the automotive engineering industry, simulations are very time-consuming themselves and have to be carried out multiple times to increase performance of small parts or larger systems. Therefore analysis as fast and as good as possible is needed to minimize the number of cycles of simulations to produce final results. In previous work we have presented visualization techniques that provide engineers with a high degree of inter-activity and flexibility for analyzing this kind of simulation results. In this case study we apply our techniques and demonstrate how users benefit from using them during their routine analysis, as well as for exploring new phenomena. For coping with some of the special requirements in this application, we adapted and extended parts of the system. A comparison of two related cases of a diesel exhaust system is presented, and some important questions about these cases are addressed. 1.
