    Computing power increases constantly. While the fastest supercomputer in 1993 had a performance of 59.7 GFlop/s, we are now clearly in the petascale era with twenty installations breaching the 1 PFlop/s barrier (see TOP500 Supercomputer Sites). Along with the computing power, the size and complexity of simulation results is increasing as well. In many...

    Our paper “Advected Tangent Curves: A General Scheme for Characteristic Curves of Flow Fields” has been accepted at EuroGraphics 2012. In this paper, we present the first general scheme to describe all four types of characteristic curves of flow fields – stream, path, streak, and time lines – as tangent curves of a derived...

    Our paper “A Benchmark for Evaluating FTLE Computations” has been accepted to PacificVis 2012. In this paper, we propose a general benchmark for FTLE computation, which consists of a number of 2D time-dependent flow fields and error measures. To this end, we also introduce approaches to create non-trivial vector fields with a closed-form formulation...
