advector

The advector module combines streamlines capability and a tool for sequential positioning of glyphs along the streamlines trajectory to simulate advection of weightless particles through a vector field (for example, a fluid flow simulation such as modflow). The result is an animation of particle motion, with the particles represented as any EVS geometry (such as a jet or a sphere). The glyphs can scale, deflect or deform according to the velocity vector it passes. At least one of the nodal data components input to advector must be a vector. The direction of travel of streamlines can be specified to be forwards (toward high vector magnitudes) or backwards (toward low vector magnitudes) with respect to the vector field. The input glyphs travel along streamlines (not necessarily visible in the viewer) which are produced by integrating a velocity field using the Runge-Kutte method of specified order with adaptive time steps.
