openpiv
Particle Image Velocimetry (PIV) analysis with OpenPIV. Use when extracting velocity fields from PIV image pairs, analyzing fluid dynamics or flow visualization experiments, cross-correlating interrogation windows, validating and replacing spurious PIV vectors, or computing vorticity, strain rate, and turbulence statistics from measured velocity fields.

# OpenPIV
## Overview
OpenPIV (Open Particle Image Velocimetry) analyzes fluid flow from PIV image pairs. It covers
preprocessing, cross-correlation, vector validation, outlier replacement, smoothing, and scaling to
physical units.
Everything below is verified against **openpiv 0.25.4**. The API moves between releases — check
`inspect.signature()` before trusting a snippet against a different version.
## When to use
Use this skill when working with experimental PIV or flow-visualization image pairs: measuring 2D
