vortexfinder2

vortexfinder2 provides tools to analyze and visualize vorticies in time-dependent Ginzburg-Landau (TDGL) superconductor simulation data. Output data from two simulation models are supported, namely GLGPU and Condor2. GLGPU and Condor2 are based on structured grid and unstructured grid, respectively.

The software is part of the OSCON (Optimizing Superconductor Transport Properties through Large-Scale Simulation) project for the Scientific Discovery through Advanced Computing Institutes.
