When to use it
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.Example requests
Ask your agent in plain language, for example:- “How do I get a velocity field out of two PIV frames?”
- “I have two TIFFs from our water-tunnel run, cyl_0001_a.tif and cyl_0001_b.tif, dt = 0.5 ms, and the calibration is 12 px/mm. I used multi-pass in windef with settings.dt set, but my u,v are still around 4 – this looks like pixels, not mm/s. What’s wrong, and how do I validate the vectors afterwards? I used a (-30, 30) limit.”
- “I’ve got a grid of 2D velocity vectors measured from seeded flow around a cylinder. I want to know where the flow is rotating and how much, and whether the field is turbulent. What should I compute and how should I be careful?”
