Turbulence is complex. Analysis shouldn't be.
uPrime is a standalone desktop application for post-processing and turbulence analysis of velocity field data from PIV and CFD. No scripting. No setup. Just analysis.
Key Features
⚡ Non-blocking computation
All heavy analysis runs in background threads. The window stays fully responsive during POD, DMD, TKE budget, and vortex identification.
💾 Large dataset support
Datasets exceeding 4 GB are automatically memory-mapped to disk. Handle 10,000+ snapshots without running out of RAM.
🎭 Non-destructive masking
Draw masks over walls, shadows, and reflections. Raw data is never modified — toggle masks on and off instantly.
🔍 Unit auto-detection
Reads mm/m/s units directly from Tecplot .dat file headers. No manual configuration needed.
📄 Publication-ready export
PNG (300 DPI), PDF, and SVG with editable text. Compatible with Adobe Illustrator and Inkscape.
🖥️ Standalone executable
Windows .exe with no Python or dependencies required. macOS and Linux users run from source in three commands.
📐 Transform & Alignment
Correct camera misalignment, shift the coordinate origin, and mirror datasets. Built for experimental data where even a 1° tilt can corrupt turbulence statistics.
🧠 Full turbulence pipeline
Reynolds stresses, TKE budget, spectra, POD, DMD, correlations, and vortex identification — all in one environment, no MATLAB or Python required.
📏 Integral scales & correlation
Compute spatial and temporal correlations with automatic integral length and time scale extraction using multiple robust methods.
