Interactive visualization of CFD data with ISVAS

ISVAS (interactive System for visual data Analysis) is an end-user visualization syste for finite-element analysis and for volume data. The system supports methods that allow an interactive analysis of very large data sets as they are commen in computational fluid dynamics (CFD). The paper presents visualization strategies as well as their realization in ISVAS. The concepts of interaction for configuration and control are outlined. Beside this user-interaction for configuration and control are outlined. Beside this user-interaction with application data by means of specification of the view point, positioning of slices, data probing, and intuitive positioning of seed points for particle tracing are some of the main characteristics of ISVAS.
