AgniKawach — Roadmap

0 Infrastructure foundation ~ 90 % SUBSTANTIALLY DONE

HazmatDB, CoolProp, RADCAL WSGGM tables, Mie tables (drafted), radiation solver, AKSource tensor + production LUT.

HazmatDB — substance properties, MW, η, Le for ~120 species (JSON-externalised 2026-05-18)
CoolProp adapter — real-fluid EOS, VLE, TTSE table caching
WSGGM (RADCAL) — gas absorption coefficient with composition selection
Radiation MC solver — 4 modes; Cumber 2009 audit closed; speed pack S2/S3/S4 — see Tier-2 → Radiation
Production AKSource LUT — 14 MB HDF5, 11.5 M cells (2026-05-18)

1 Tier-1 complete · QRA v1.0 · AKSource unified stack ~ 90 % SUBSTANTIALLY DONE

Integral models for all 8 consequence types + QRA / LOPA / regulatory packs + unified source-modelling tensor.

28 modules in solvers/tier1/ — see Tier-1 reference
534 tests green (2026-05-18) including 269 AKSource P0-P12 + 41 G-batch + 19 follow-up + 50 C++ kernels — see coverage
Regulatory packs — PNGRB · OISD · COMAH · Seveso-III all PASS — see ERDMP guide
AKSource (2026-05-17/18) — tier-spanning source tensor + vessel ODE + MTT hand-off + multi-source superposition + REST dispatch + JWT auth. Williamson BLEVE matches published 58.0 m exactly.
Remaining — crosswind / meander corrections, full Mudan integral, AERMOD PRIME terrain (see Tier-1 upcoming)

2 Tier-2 dispersion · geometry ~ 75 % CURRENT

VC-002 → EB-004 V&V cases; semi-implicit Brinkman; Boussinesq-MW; 5 in-tree patches.

19 / 20 dispersion cases pass Hanna FAC2 — see V&V Casebook
5 custom patches — aux-LES · D(x) ramp · turb clamp · PDR L · turb LP-filter
Three composable geometry paths — EB · Brinkman+IBM · PDR — see Tier-2 → Geometry
Items 1–5 dispersion bundle (2026-05-04) — VOS Brinkman, EB wall fn, spike softener, substepping, AMR+turb preflight
Open — anisotropic dz blocked by Setup.cpp:48; AMR + TurbInflow CFL collapse

Phase-2 close criteria. All four open dispersion gaps closed: anisotropic dz lift, AMR + turb spectral filter validated, anelastic buoyancy, EB wall-function landed.

3 Tier-2 fire — pool + jet ~ 30 % IN BUILD-OUT

Standalone radiation matured (P1 + 4-mode MC + WSGGM + soot). Patch 0008 combustion kernels (TFC/EDC/Detonation/Fireball) land 2026-05-18.

16 / 27 radiation cases ± 15 % wall flux — VC-R001 periodic-axis fix landed 2026-05-06; RULES v2 + Altaç-Tekkalmaz buildout 2026-05-14
Patch 0008 combustion kernels (2026-05-18) — TFC · EDC · Detonation · Fireball; smoke-clean
Lagrangian spray bridge (2026-05-18) — Python translator + ParmParse contract; full C++ linkage deferred
Soot — Brookes-Moss two-equation; Rayleigh κ already in radiation properties
NIST firemodels/exp — to curate to solvers/vv/datasets/firemodels_exp/
Blocker — A100 spot job runner (see Phase 0 carry-over)

4 Tier-2 explosion · BLEVE · flash fire — % QUEUED

PeleC compressible reactive flow. PDR is required at coarse grid for industrial congestion.

AKExplosionSolver / AKMEMModel — stubs in tree; fed by Tier-1 CAM front door
AKBLEVESolver — coupled compressible + radiation; Tier-1 TwoPhaseFlash inlet state
Cryogenic LNG — PeleMP Lagrangian spray + low-Mach gas phase

5 QRA workbench v2.0 ~ 40 % PROTOTYPE

F-N curves, LOPA, GIS contours. Frontend prototype already in tree at qra_dashboard.html.

QRA Dashboard — risk contours, F-N curve, event tree, wind-rose batch — built
LOPA workbench — IPL PFD aggregation; SIF sizing input
GIS contour export — to land in v2.0

6 GPU Monte Carlo radiation — % DEFERRED · RESEARCH

Move MC ray-tracing to CUDA kernels. Sobol + hot-ray already vectorisable; the win is the tracking kernel.

∗ Compute orchestration (AWS A100 spot runner) P0 BLOCKER

K8s + Karpenter spot job runner pulling scenario JSON, building PeleLMeX with USE_CUDA = TRUE, shipping plotfiles to S3. Required to unlock the ₹2 500 — 8 000 / hr A100 cost model. Not solver work but blocks Phase 3 graduation and the live frontend pipe (see coverage gaps).
