Browser-based utilities for Particleworks CFD simulation workflows
Downgrade scene JSON files from v8.2.x to v8.1.0 format. Removes deprecated keys, restores 8.1 defaults, cleans per-object properties.
Upload velocity field data and visualize 25+ interactive plots: spatial structure, density, distributions, direction analysis, and uniform grid regridding.
Drag-and-drop probe_regions.csv files, auto-detect regions, plot flowrate/volume/velocity/temperature with per-region direction controls and multi-group support.
Upload up to 5 scene JSONs, compute a structured diff client-side, then get a detailed LLM-powered analysis of all differences via Llama 3.3 70B.
Upload a Particleworks scene JSON (v8.2.x) and the backend worker will convert it to v8.1.0 format using the original Python script.

Upload a velocity field file with columns: idx x y z vx vy vz
Tab, space, or comma separated. First column (index) is skipped.

| nparticles | number of particles in probe region |
| lprobe [m] | length/thickness of probe = thickness_dp × PS (at least 3-5 particle diameters) |
| u⊥ [m/s] | perpendicular average velocity of particles (in flow direction) |
| Vfluid [m³] | fluid volume per particle = PS³ |
| V̇ [m³/s] | volumetric flow rate |
The region name suffix encodes direction and thickness: e.g. inner_flow-x-2 = velocity.x component, 2 particle diameters thick. Override via the Direction and l_probe fields.
Upload 2-5 Particleworks scene JSONs — client-side diff + Llama 3.3 70B analysis of all differences.
