Particle tracing in time-varying flow fields is traditionally performed by numerical integration
of the underlying vector field. This procedure can become computationally expensive …

Abstract Chandler et al.[COJ15] presented interpolation-based pathline tracing as an
alternative to numerical integration for advecting tracers in particle-based flow fields and …

The parallel vectors (PV) operator is a feature extraction approach for defining line‐type
features such as creases (ridges and valleys) in scalar fields, as well as separation …

Lagrangian coherent structures (LCSs) have become a widespread and powerful method to
describe dynamic motion patterns in time‐dependent flow fields. The standard way to extract …

As an alternative to conventional Eulerian methods in the field of computational fluid
dynamics (CFD), smoothed particle hydrodynamics (SPH) has been developed. Its mesh …

Feature extraction is an essential aspect of scientific data analysis, as it allows for a data
reduction onto relevant structures. The extraction of such features from scalar and vector …

Smoothed particle hydrodynamics (SPH) is a completely mesh-free method to simulate fluid
flow (Gingold & Monaghan, 1977; Lucy, 1977). Rather than representing the physical …

Interactive visualization of large particle sets is required to analyze the complicated
structures and formation processes in astrophysical particle simulations. While some …

Direct visualization of higher-order data provides manifold advantages over the traditional
approach, which is based on resampling and subsequent visualization by interpolation …

The paper describes the software tool SmoothViz designed for visual representation and
interactive analysis of data coming from SPH simulations with astrophysics as the driving …
