Identifying Locally Turbulent Vortices within Instabilities
Fabien Vivodtzev, Florent Nauleau, Jean-Philippe Braeunig +1
This work presents an approach for the automatic detection of locally turbulent vortices within turbulent 2D flows such as instabilites. First, given a time step of the flow, metho…
A Practical Solver for Scalar Data Topological Simplification
Mohamed Kissi, Mathieu Pont, Joshua A. Levine +1
This paper presents a practical approach for the optimization of topological simplification, a central pre-processing step for the analysis and visualization of scalar data. Given…
Parallel Computation of Piecewise Linear Morse-Smale Segmentations
Robin G. C. Maack, Jonas Lukasczyk, Julien Tierny +3
This paper presents a well-scaling parallel algorithm for the computation of Morse-Smale (MS) segmentations, including the region separators and region boundaries. The segmentation…
Topological data analysis of vortices in the magnetically-induced current density in LiH molecule
Małgorzata Olejniczak, Julien Tierny
A novel strategy for extracting axial (AV) and toroidal (TV) vortices in the magnetically-induced current density (MICD) in molecular systems is introduced, and its pilot applicati…
Topological Analysis of Ensembles of Hydrodynamic Turbulent Flows -- An Experimental Study
Florent Nauleau, Fabien Vivodtzev, Thibault Bridel-Bertomeu +2
This application paper presents a comprehensive experimental evaluation of the suitability of Topological Data Analysis (TDA) for the quantitative comparison of turbulent flows. Sp…
Principal Geodesic Analysis of Merge Trees (and Persistence Diagrams)
Mathieu Pont, Jules Vidal, Julien Tierny
This paper presents a computational framework for the Principal Geodesic Analysis of merge trees (MT-PGA), a novel adaptation of the celebrated Principal Component Analysis (PCA) f…
