|---|---|---|
This work presents interactive flow visualization techniques specificallyadapted for PowerFLOW, a lattice-based CFD code fromthe EXA corporation. Their Digital Physics fluid simulationtechnique is performed on a hierarchy of locally refined cartesiangrids with a fine voxel resolution in areas of interesting flow features.Among other applications the PowerFLOW solver is usedfor aerodynamic simulations in car body development where the advantagesof automatic grid generation from CAD models is of greatinterest. In a joint project with BMWand EXA we are developing avisualization tool which incorporates virtual reality techniques forthe interactive exploration of the large scalar and vector data sets.In this paper we describe the specific data structures and interpolationtechniques and we report on fast particle tracing taking intoaccount collisions with the car body geometry. An OpenGL Optimizerbased implementation allows for the inspection of the flowwith particle probes and slice probes at interactive frame rates. |
