Particle-Trace Visualization Technique.

Abstract

Particle tracing is a visualization technique that gives to the observer the simultaneous perception
of direction and velocity of the flow. An efficient algorithm is presented allowing the computation of
particle trajectories for unsteady flows in moving meshes, including also the computation of skin-friction
particles, i.e. particles bound to the body skin. Visualization with the OpenDX package, as well as the
parallel implementation in SMP architectures is also described. Discussion of visualization parameters,
as particle density, and frame rate in order to avoid coherence effect is discussed
