A fully automatic feature detection algorithm is presented that locates and distinguishes lines of flow separation and attachment on surfaces in 3D numerical flow fields. The algorithm is based on concepts from 2D phase-plane analysis of linear vector fields. Unlike prior visualization techniques based on particle tracing or flow topology, the phase-plane algorithm detects separation using local analytic tests. The results show that it not only detects the standard closed separation lines but… CONTINUE READING
