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.

Targets openpiv 0.26.1. Synthetic checks ran on Python 3.13, NumPy 2.5.3, SciPy 1.18.1, scikit-image 0.26.0, and Matplotlib 3.11.2. Rust was not installed; use backend="scipy" for the tested path. See review evidence.

When to use

Use this skill when working with experimental PIV or flow-visualization image pairs: measuring 2D velocity fields, tuning interrogation-window parameters, validating vectors, or deriving vorticity, strain rate, and turbulence statistics. For simulating flow rather than measuring it, use a CFD skill instead.
