Hexanta plots from Simulex output

**Persons out over time (15 native runs)**Cumulative persons out per 5-second bin for all 15 hotel runs, coloured by scenario; drawn by Hexanta from the Simulex results text files. Hypothetical building, assumed inputs.Hexanta plot of evidence values · source: simulex-HXM01-20261024/raw/*/HXM01-*.txt (5-second exit flow bins)

**Total evacuation time per run and mean**Each dot is one native Simulex run (3 per scenario); the bar is the Hexanta-derived mean.Hexanta plot of evidence values · source: simulex-HXM01-20261024/raw/*/HXM01-*.txt (total time line)

**Exit use and peak specific flow**Left: mean persons per exit (Simulex counts). Right: peak specific flow derived by Hexanta (largest 5-second count ÷ 5 s ÷ width) against the analysis's 1.3 queueing indicator. Densities are not in the Simulex output.Hexanta plot of evidence values · source: simulex-HXM01-20261024/raw/*/HXM01-*.txt (per-exit 5-second bins, exit widths)

Simulex playback (ALT-WARN, first run) and result

**Playback, ALT-WARN first run — 0:40.1**Frame from Simulex's playback of the recorded run at simulated time 0:40.1: occupants still in their cabins (response not yet complete).Screenshot of the native tool (static image) · source: simulex-JOB-20261024/shots/HXM01-ALT-WARN-A1-pbf-001.png (cropped; time from out/HXM01-ALT-WARN-A1-frames.tsv)

**Playback, ALT-WARN first run — 2:26.8**Simulated time 2:26.8: some occupants have left; others are crossing the courtyard.Screenshot of the native tool (static image) · source: simulex-JOB-20261024/shots/HXM01-ALT-WARN-A1-pbf-007.png (cropped)

**Playback, ALT-WARN first run — 4:14.0**Simulated time 4:14.0: the last occupants, the latest to respond, are still in their cabins.Screenshot of the native tool (static image) · source: simulex-JOB-20261024/shots/HXM01-ALT-WARN-A1-pbf-013.png (cropped)

**Simulex end-of-run message (ALT-WARN, first run)**Simulex's own completion message for run HXM01-ALT-WARN-A1: all people reached the exit in 5:27.0 (327.0 s).Screenshot of the native tool (static image) · source: simulex-HXM01-20261024/shots/HXM01-ALT-WARN-A1-07-result.png (cropped)

Note

Screenshots are cropped still images of Simulex's own window; they are not an interactive model.

Sanitised derivative of preserved evidence (simulex-HXM01-20261024, simulex-HXO01-20261024-r2, simulex-JOB-20261024). Plots and the report were drawn by Hexanta from values in the Simulex results files; screenshots are cropped and visually reviewed. Nothing was re-simulated. · Pack la-hotel-evacuation-r3 (built 2026-10-25); every file is checked against its SHA-256 before it is shown.
