# Reference Model 문서 작성 가이드
|
|
|
|
이 디렉터리는 Reference Model Agent가 작성하거나 제안한 기능별 reference model 설계 문서를 보관하는 위치다.
|
|
|
|
Reference Model Agent는 FESA 기능 검증에 필요한 Abaqus `.inp` 기반 테스트 모델 포트폴리오와 `references/<feature-id>/<model-id>/` artifact bundle 계약을 정의한다. Agent는 Abaqus, Nastran 또는 레퍼런스 솔버를 직접 실행하지 않고, reference HDF5 artifact나 reference CSV 값을 생성하지 않으며, solver 결과 비교나 release readiness 승인도 하지 않는다.
|
|
|
|
기본 파일명은 `docs/reference-models/<feature-id>-reference-models.md` 형식을 사용한다. 각 문서는 요구조건, 연구 브리프, 정식화, 수치 리뷰, I/O 정의를 입력으로 받아 구현 전에 준비해야 할 테스트 모델과 reference artifact 요구사항을 정의해야 한다.
|
|
|
|
## Reference Model Agent 역할
|
|
|
|
수행한다:
|
|
- 기능별 reference model portfolio를 smoke, analytical, patch test, benchmark, regression, negative/invalid-input model로 구분한다.
|
|
- `model.inp`가 I/O Definition Agent의 supported Abaqus keyword subset 안에 있는지 확인한다.
|
|
- `references/<feature-id>/<model-id>/` artifact bundle 구조와 필수 파일을 정의한다.
|
|
- `metadata.json` provenance, 단위, 좌표계, Abaqus version/source, output request, HDF5 schema version, tolerance 정책을 정의한다.
|
|
- `results.h5` 또는 feature-specific HDF5 reference result file 요구사항을 정의한다.
|
|
- upstream 요구조건이 명시한 경우에만 `displacements.csv`, `reactions.csv`, `element_forces.csv`, `stresses.csv` 같은 optional CSV export 요구사항을 정의한다.
|
|
- requirement와 model, compared quantity, tolerance, artifact status를 연결하는 Coverage Matrix를 작성한다.
|
|
|
|
수행하지 않는다:
|
|
- C++ 코드를 구현하지 않는다.
|
|
- parser를 구현하지 않는다.
|
|
- C++ API나 파일 구조를 설계하지 않는다.
|
|
- Abaqus, Nastran 또는 레퍼런스 솔버를 직접 실행하지 않는다.
|
|
- reference HDF5 artifact 또는 reference CSV를 생성하지 않는다.
|
|
- solver 결과를 비교하지 않는다.
|
|
- release readiness를 승인하지 않는다.
|
|
- reference 값, tolerance, Abaqus compatibility를 임의로 만들지 않는다.

|
|
|
|
## Artifact Bundle Contract
|
|
|
|
```text
|
|
references/
|
|
<feature-id>/
|
|
<model-id>/
|
|
model.inp
|
|
metadata.json
|
|
results.h5
|
|
README.md
|
|
```
|
|
|
|
Required files:
|
|
- `model.inp`: Abaqus input file for the reference model.
|
|
- `metadata.json`: provenance and model contract metadata.
|
|
- `results.h5`: HDF5 reference result artifact containing required metadata, mesh, step/frame, nodal, element, field, and history result datasets.
|
|
- `README.md`: short description, generation notes, and limitations.
|
|
|
|
Optional files:
|
|
- `displacements.csv`: nodal displacement export when upstream contracts explicitly require CSV.
|
|
- `reactions.csv`: nodal reaction force export when upstream contracts explicitly require CSV.
|
|
- `element_forces.csv`: element internal force export when upstream contracts explicitly require CSV.
|
|
- `stresses.csv`: stress export when upstream contracts explicitly require CSV.
|
|
- `strains.csv`: strain reference results when required.
|
|
- `energy_or_residual.csv`: energy, residual, or convergence reference results when required.
|
|
- `notes.md`: manual review notes.
|
|
|
|
For the current `mitc4-linear-static-shell` feature, the required stored Abaqus artifacts are:
|
|
|
|
```text
|
|
references/mitc4-linear-static-shell/<model-id>/
|
|
model.inp
|
|
metadata.json
|
|
abaqus_s4r/results.h5
|
|
abaqus_s4/results.h5
|
|
README.md
|
|
```
|
|
|
|
`abaqus_s4r/results.h5` is the primary pass/fail reference. `abaqus_s4/results.h5` is diagnostic.
|
|
|
|

## Reference HDF5 Requirements
|
|
|
|
- Required when reference comparison is part of the feature acceptance criteria.
|
|
- Must include metadata, mesh identity, step/frame identity, node and element IDs, component names, coordinate system, units, output locations, and tolerance source.
|
|
- Required quantity datasets must match the paths and component contracts from `docs/io-definitions/<feature-id>-io.md`.
|
|
|
|
## Optional CSV Export Requirements
|
|
|
|
CSV exports are not required for the current HDF5-first MITC4 feature unless an upstream document explicitly requires them. When required, they must preserve the same physical meaning and matching keys as the HDF5 datasets.
|
|
|
|
### displacements.csv
|
|
- Required when nodal displacement is a verification quantity.
|
|
- Must include step/frame identity, node id, displacement components, coordinate system, and units.
|
|
|
|
### reactions.csv
|
|
- Required when constrained DOF reactions or global equilibrium are verification quantities.
|
|
- Must include step/frame identity, node id, reaction components, coordinate system, and units.
|
|
|
|
### element_forces.csv
|
|
- Required when element internal force is a verification quantity.
|
|
- Must include step/frame identity, element id, output location, component, value, and units.
|
|
|
|
### stresses.csv
|
|
- Required when stress is a verification quantity.
|
|
- Must include step/frame identity, element id, integration point or recovery location, component, value, coordinate system, and units.
|
|
|
|
### Optional CSVs
|
|
- `strains.csv`: required when strain is part of the acceptance criteria.
|
|
- `energy_or_residual.csv`: required when energy balance, residual, or convergence data is part of the acceptance criteria.
|
|
|
|
## Coverage Matrix
|

|
|
| requirement_id | model_id | compared_quantity | artifact_file | tolerance | verification_method | status |

|
|
| <req-id> | <model-id> | reaction | results.h5:/results/.../nodal/reaction | <policy> | reference-comparison | draft |

|
|
|
|
## Artifact Acceptance Checklist
|
|
- 모든 `must` requirement가 최소 하나의 `model_id`와 `compared_quantity`에 연결되어 있다.
|
|
- `model.inp`가 기능별 supported Abaqus keyword subset을 벗어나지 않는다.
|
|
- `metadata.json`에 provenance, Abaqus version/source, units, coordinate system, tolerance, HDF5 schema version이 기록되어 있다.
|
|
- 필수 HDF5 artifact가 존재하거나, 기능상 불필요한 파일은 명확한 reason과 함께 제외되어 있다.
|
|
- output request가 필요한 HDF5 물리량을 생성할 수 있도록 정의되어 있다.
|
|
- reference HDF5 artifact가 없으면 status는 `needs-reference-artifacts`다.
|
|
- tolerance, source, units, coordinate system이 불명확하면 status는 `needs-user-decision`이다.
|
|
|
|
## Open Issues and Downstream Handoff
|
|
|
|
### I/O Definition Agent
|
|
- <supported keyword, output request, HDF5 schema clarification>
|
|
|
|
### Implementation Planning Agent
|
|
- <tests that should fail before implementation, model order, acceptance criteria>
|
|
|
|
### Reference Verification Agent
|
|
- <HDF5 schema, optional CSV schema, ID matching, units, coordinate conventions, output locations, tolerance mapping>
|
|
|
|
### Physics Evaluation Agent
|
|
- <equilibrium, symmetry, displacement direction, stress location, rigid body mode, load path sanity checks>
|
|
```
|
|
|
|
## 품질 기준
|
|
|
|
- Reference model의 목적과 검증 대상 requirement가 명확해야 한다.
|
|
- `model.inp`는 Abaqus input file이며, 기능별 supported keyword subset을 따라야 한다.
|
|
- model data와 history data를 구분해야 한다.
|
|
- output request와 required HDF5 dataset 사이의 연결이 명확해야 한다.
|
|
- `references/<feature-id>/<model-id>/` 구조와 필수 artifact가 명시되어야 한다.
|
|
- `metadata.json`에는 provenance, Abaqus version/source, units, coordinate system, tolerance, HDF5 schema version이 포함되어야 한다.
|
|
- reference HDF5 artifact가 없으면 완료 상태가 아니라 `needs-reference-artifacts` 상태로 둔다.
|
|
- 모든 `must` requirement는 Coverage Matrix에서 model, compared quantity, tolerance, verification method로 추적되어야 한다.
