Archive Summary — 2026-02-10

Biggest single day of Hydrotech Beam work. Full details archived from daily log at 30-day threshold.

Key Events

• Received 3 KBS capture sessions from Antoine (NX/Simcenter walkthrough of Hydrotech Beam model)
• Tech Lead processed sessions → KB Gen 002 update (commit b88657b)
• Mass corrected to 1,133.01 kg (p173) — Antoine correction, ground truth
• Binary introspection of Beam.prt → full expression table extracted (commit 15a457d)
• DV baselines confirmed NOT round: face_thickness=21.504, core_thickness=25.162
• beam_lenght has TYPO in NX (no 'h') — must use exact spelling
• Gaps G12-G14 closed

Optimization Pipeline Built (Full Chain)

1. Optimizer updated strategy with corrected baselines (commit 3e51804)
2. Auditor reviewed → APPROVED WITH CONDITIONS (hole spacing formula + web height constraint fixed, commit 94bff37)
3. Study Builder completed Phase 1 code: run_doe.py, sampling.py, geometric_checks.py, nx_interface.py (commit 017b90f)
4. Study Builder delivered NXOpenSolver wrapper around existing Atomizer engine (commit 33180d6)
5. Tech Lead refined NXOpenSolver v2 with auto-detection + fallbacks (commit 390ffed)
6. Antoine tested on dalidou → 2 bugs fixed (commit 135698d)
7. Full refactor of nx_interface.py → AtomizerNXSolver (commit 126f0bb)

Key Technical Facts (Preserved)

• Beam: 5,000mm length, cantilever (left fixed, right 10,000 kgf down)
• Hole span = 4,000mm (p6), kept fixed (Manager decision)
• Material: ANSI Steel 1005 (future: aluminum 6061, stainless ANSI 310)
• Mesh: CQUAD4 thin shells, mid-surface idealization, element size 67.4/2
• Conda env: atomizer on Windows (dalidou), all deps pre-installed
• Windows path: C:\Users\antoi\Atomizer\projects\hydrotech-beam\
• Existing engine reused: NXSolver + NXParameterUpdater + pyNastran extractors

Infra Fixes

• Study Builder model corrected (claude-sonnet-5 → claude-sonnet-4-20250514)
• API auth propagated to all agents from Manager's auth-profiles.json

CEO Requests Logged

• NX Simcenter 3D MCP server — Phase 2/3 roadmap item

Open at EOD

• Antoine to test --backend nxopen smoke test on dalidou
• Full 51-trial Phase 1 run pending
• Phase 2 TPE optimization pending
