Purpose

이 파일은 여러 AI Agent가 같은 작업을 이어받을 때 현재 목표와 실행 계획을 빠르게 파악하기 위한 공유 계획서이다.

Current Objective

3D Euler-Bernoulli beam Abaqus/Standard UEL 구현을 하네스 phase 흐름에 따라 진행한다.

Active Phase

• Phase directory: phases/uel-3d-euler-beam
• Current planned entry point: python scripts/execute.py uel-3d-euler-beam
• First pending action: correct Abaqus-facing UEL wrapper/interface mismatch before step8 validation readiness

Planned Steps

1. Requirements: docs/requirements/uel-3d-euler-beam.md
2. Research: docs/research/uel-3d-euler-beam-research.md
3. Formulation: docs/formulations/uel-3d-euler-beam.md
4. Numerical review: docs/numerical-reviews/uel-3d-euler-beam.md
5. Interface contract: docs/io-definitions/uel-3d-euler-beam.md
6. Test/reference model plan: docs/reference-models/uel-3d-euler-beam.md
7. RED no-Abaqus Fortran tests and manifest - completed
8. GREEN Fortran implementation - completed
9. Validation, physics sanity, and readiness audit - next

Success Criteria

• Every must requirement has verification method, acceptance criteria, and tolerance or decision owner.
• Fortran production changes follow RED -> GREEN -> VERIFY.
• No-Abaqus tests pass through python scripts/validate_fortran.py when compiler and manifest are available.
• Workspace validation passes through python scripts/validate_workspace.py.
• Solver-result validation is marked complete only after externally generated ODB-extracted CSV artifacts are provided and validated.

Out Of Scope Until Explicitly Approved

• Running Abaqus jobs from this repository.
• Direct ODB parsing in this repository.
• Fabricating reference CSV, .msg, .dat, .log, or .sta evidence.
• Geometric nonlinearity, Timoshenko shear deformation, mass, damping, distributed loads, plasticity, damage, thermal strain, warping torsion, and section offsets for the first UEL implementation.

Open Decisions

• Confirm exact first-scope beam assumptions in the requirements step.
• Decide PROPS/JPROPS ordering and orientation-vector convention in the interface step.
• Decide exact no-Abaqus Fortran source and test file layout in the reference model step.
• Add a top-level Abaqus-callable SUBROUTINE UEL(...) wrapper and correct the VARIABLES/NSVARS policy before external Abaqus validation readiness.
