OpenPIV is the community driven initiative to develop free and open-source software for Particle Image Velocimetry (PIV) image analysis and post-processing.

OpenPIV is the successor of the popular URAPIV software, but it is faster, more user-friendly and much more flexible.

OpenPIV exists in three languages and various versions: Matlab, Python, C++ with Qt-based GUI, and GPU accelerated version.

OpenPIV is not only the PIV image analysis software. It is a fully integrated solution from an experiment to a publication. We provide an integrated Matlab toolbox for Spatial and Temporal PIV data analysis that provides time and spatial analysis, e.g. velocity profiles, spatial correlations, FFT, contours of vorticity, etc. Moreover, we provide the insightful Proper Orthogonal Decomposition (POD) Toolbox that gives you a deep insight into the most energetic coherent structures and meaningful patterns of the flow.
