Topology-guided Visualization of Constrained Vector Fields

In Topology-Based Methods in Visualization, Springer Berlin Heidelberg, pp. 21–33, 2007.


In this study we explore ways of using precomputed vector field topology as a guide for interactive feature-based visualization of flow simulation data. Beyond streamline seeding based on critical points, we focus mainly on computing special stream surfaces related to critical points and periodic orbits. We address the special case of divergence-free vector fields which is often met in practical CFD data, and we extend the topological analysis to no-slip boundaries by treating 3D velocity and 2D wall shear stress in a unified way. Finally we apply the proposed techniques to flow simulation data and demonstrate their usefulness for the purpose of studying recirculation and separation phenomena.
