Consequence modelling
Dispersion, fires, explosions on the site.

Screenshots and a short video come with the listing (AL.3).
Overview
Planned. This add-on is not built and no host app mounts it. Consequence modelling is planned (roadmap row CH.16) as screening estimates of releases, toxic and flammable dispersion, jet and pool fires and vapor cloud explosions, shown as zones on the CivilCraft site plan and in BimCraft 3D. The roadmap states the intent honestly as screening, not CFD-grade. A library exists in the lab; no app draws its zones yet.
Who it’s for
- Process safety engineers doing screening studies.
- Site planners who want hazard zones shown on the real site and buildings.
What you can do
- Nothing works yet. Planned: release rate and flash for liquid and gas, pool evaporation, a Gaussian plume, jet and pool fire radiation, TNT-equivalence blast overpressure, and zones drawn on the site plan or in 3D (CH.16).
Methods and standards
Planned from published screening equations. The library's plume code is shared with the air dispersion add-on. Its session log lists models not built: heavy-gas dispersion, multi-energy blast, BLEVE, two-phase rainout, puffs, obstacles and terrain, and indoor releases.
Data and sources
Endpoint levels, radiative fraction, explosion yield and probit constants are your inputs; no default is supplied. The plant model supplies the release streams.
Verification
Planned: no add-on test yet. The engine library behind it has a test, tools/process-test/test-safety.mjs, which the session log chem-safety_PART_3 records as 151 passed, 0 failed on 2026-10-28. It checks the library's arithmetic and file handling, not an add-on, and not against a worked example from a published guideline. The log lists the plume sigmas, pool evaporation, flame height and blast constants as typed and not confirmed.
Limits
Screening only. Not built: the models listed above, and any CivilCraft or BimCraft command that draws the zones; the library only produces the zone shapes as data. It is not a substitute for a specialist study.
Files and formats
Planned: zone shapes for the site plan and 3D volumes. No file is written by an app today.
Get started
- Nothing to open yet. The add-on is planned and cannot be added.
- Watch the roadmap row named in this listing for when it is built and enters the lab.
