Ein Softwaresystem zur parallelen interaktiven Stroemungssimulation und -visualisierung

The development of increasingly complex hydrodynamic numerical models is necessary for effective scientific research. This is especially the case for instationary multidimensional problems. Computer graphics has become an indispensable and extremely effective tool for this purpose. This thesis presents various concepts concerning an interactive user interface for a parallel simulation with graphic analysis. Computer capabilities are utilized in a network in order to achieve high computational efficiency by the parallel handling of different processes on the computers in the network. The verification of hydrodynamic simulations and transport processes is a further time-consuming problem, demanding a great deal of experience on the part of the user. It is thus of great advantage if the user always has direct control over the simulation and is able to intervene during the course of the simulation interactively. The graphic structure should be such as to permit quick interactive intervention and should provide an overall view of the distribution of selected physical parameters, such as e.g. velocity or concentration. The results of numerical experiments are discussed using different colour tables and colour scales. It is shown that new software concepts can contribute to get research results in numerical fluid dynamics.
