Built for labs, classrooms, and engineering workflows
Turn particle motion into measurable velocity fields.
PIV Analyzer focuses on a practical desktop workflow: import image pairs or videos, tune PIV parameters, inspect the resulting flow field, and export visual or numeric data for reports, papers, and follow-up analysis.
Velocity visualization
Overlay arrows, heatmaps, contours, and displacement-color maps on original frames for fast interpretation and presentation.
Region control
Set calculation regions and exclusion masks so the analysis focuses on the flow area that matters.
Research exports
Save processed frames, annotated videos, CSV files, and Excel workbooks for publication figures or downstream analysis.
Workflow
From raw frames to exportable results.
- 1Import particle image pairs, image sequences, or video.
- 2Set time interval, scale, interrogation window, overlap, and filtering.
- 3Run PIV processing and inspect velocity vectors across frames.
- 4Export visual overlays, videos, and numeric velocity data.
Example output
Visualize direction, magnitude, and confidence.
Heatmap
Use color intensity to identify high-speed regions and gradients.
Vector field
Inspect flow direction and relative magnitude with adjustable arrow density.
Data export
Export x, y, u, v, magnitude, and correlation data for reproducible analysis.
Use cases
Designed for experimental flow analysis.
Microfluidics
Water-channel experiments
Particle tracking studies
Teaching labs
Engineering validation

Free beta
Download PIV Analyzer for Windows.
The first public version is planned as a free beta while feedback, tutorials, and validation examples are collected. A Pro license can be added later for commercial support and advanced export workflows.
