Read-only demonstration. Four sanitised or hypothetical engineering projects. Each states its own validation status; nothing shown is engineer approved.
Cropped images from the native CFD viewer (static screenshots, not interactive models) and Hexanta plots drawn from evidence values.
Optimised design - temperature, vertical slice x = 2.75 mDC00O-R1 converged field, filled temperature contour through the rack rows: cold aisle supplied from the floor (blue), hot aisles behind the racks (orange). Temperature colour key (native) 19.3-34.0 °C; the two warmest key cells are cropped off.Screenshot of the native tool (static image) · source: cfd-DC00-20261024-r2/figures/m42-DC00O-R1-x2.75-temperature.png (cropped)Baseline design - temperature, vertical slice x = 2.75 mDC00B-R5 field (final baseline R6 differs by at most 0.02 K at the monitors), same slice and view.

Rack inlet temperatures (Hexanta plot)Solver cell-monitor values at each rack inlet for the final baseline, the final optimised design and the refined mesh. Differences are about the size of the grid and sampling effect.Hexanta plot of evidence values · source: cfd-DC00-20261024-r2/study-manifest.study.json (cfd.*.racks)Annual cooling-system electricity (Hexanta plot)Chiller and fan electricity from the two annual simulations.

Sanitised derivative of preserved evidence (cfd-DC00-20261024-r2, cfd-DC01-N1-DSM-20261024). Nothing was re-simulated. Screenshot crops are static images of the native viewer; plots and the report contain only values read from the evidence. · Pack cfd-data-centre-r2 (built 2026-10-25); every file is checked against its SHA-256 before it is shown.
