Application in CFD and virtual reality simulation provide analysis of fluid flow problems in detail. These processes are faster than testing and simulates at an earlier stage in the design cycle for less cost. Integration of CFD and VR provide advance interfaces to enable visual, haptic, and audio interaction between users and computer generated virtual environments. Visual attributes can present abstract representations of data. Relationships among displayed entities become apparent.
Graphical techniques allow more direct intuitive interactions with the entities of interest.
The interactive tool in this application is using wand to select a virtual menu and by using virtual cursor to place different flow phenomenon such as streamlines, 3-D momentum profiles, contour planes, etc. Animated features included are particle tracing in streamlines and transition of different isosurface values. An octree-based data structure for viewing large unstructured grid data sets. Simplication of large unstructured data sets.
