Solver references, physics modules, workbench tools, and validation reports. Eight consequence types — dispersion, jet fire, pool fire, flash fire, VCE, detonation, BLEVE, cryogenic release — built on a shared physics backbone. Bookmark a card to jump straight in.

Solvers

Tier-1 Reference

Integral models — Gaussian, HEGADAS, Britter-McQuaid, MEM / BST, solid-flame, Chamberlain entrainment, ZND. Screening-grade results in seconds.

28 modules · 280+ tests

Tier-2 Reference

Physics modules

Unified Source Modelling

One source tensor feeds every consequence solver — vessel ODE, orifice + flash, two-phase HEM, pool spread, mixture flash, vessel burst seed. Inverse and ensemble modes for what-if and uncertainty.

13 phases · 484+ tests

Spectral Radiation

Path-tracing Monte Carlo + weighted-sum-of-gray-gases (H₂O + CO₂) + Rayleigh soot. Four sampling modes: full-field, monitor probe, hemisphere wall flux, q_inc field for fireball receivers.

28 validation cases

Combustion Kinetics

Non-premixed eddy-dissipation concept, premixed flamelet-generated manifold, ZND detonation, fireball. Stiff BDF ODE reactor — GPU- integrated chemistry.

Quality & coverage

Tests · Verification · Validation

The three pillars: 500+ unit tests across the source, geometry, radiation and dispersion modules; verification studies (MMS, conservation, grid convergence); validation against public field-trial and wind-tunnel datasets.

19 / 20 dispersion · 16 / 27 radiation

Per-case index across dispersion and radiation. Status, references, deep-links into coverage tables and the matching solver entry. Filterable by domain.
