# Sprint Contract: Dof Manager Reaction Foundation
|
|
|
|
## Objective
|
|
Rebuild or verify the six-DOF `DofManager`, constrained/free mapping, equation numbering, sparse-pattern inputs, and full-vector reconstruction needed for reaction recovery.
|
|
|
|
## Required Reading
|
|
- /AGENTS.md
|
|
- /docs/ARCHITECTURE.md
|
|
- /docs/ADR.md
|
|
- /docs/NUMERICAL_CONVENTIONS.md
|
|
- /docs/RESULTS_SCHEMA.md
|
|
|
|
## Scope
|
|
- Manage active six-DOF shell nodes.
|
|
- Apply fixed constraints by constrained DOF elimination.
|
|
- Own equation numbering and sparse connectivity inputs.
|
|
- Reconstruct full vectors in original global DOF order.
|
|
- Provide data needed for `RF = K_full * U_full - F_full`.
|
|
|
|
## Allowed Files
|
|
- `include/`
|
|
- `src/`
|
|
- `tests/`
|
|
- `PLAN.md`
|
|
- `PROGRESS.md`
|
|
|
|
## Explicit Non-Goals
|
|
- Do not assemble MITC4 stiffness.
|
|
- Do not store equation ids in `Node` or `Element`.
|
|
- Do not compute `RF` from reduced vectors only.
|
|
|
|
## Tests To Write First
|
|
- DOF activation and Abaqus component order.
|
|
- Constrained/free partition tests.
|
|
- Equation numbering stability with noncontiguous node ids.
|
|
- Full/reduced vector reconstruction tests.
|
|
- Sparse-pattern connectivity input tests.
|
|
- Full-vector reaction formula unit test with a small known matrix.
|
|
|
|
## Reference Artifacts
|
|
- None.
|
|
|
|
## Acceptance Commands
|
|
```bash
|
|
python scripts/validate_workspace.py
|
|
```
|
|
|
|
## Evaluator Checklist
|
|
- `DofManager` owns all equation numbering.
|
|
- Full-space order is deterministic and matches `UX,UY,UZ,RX,RY,RZ`.
|
|
- Reaction foundation preserves constrained DOF information.
|
|
|
|
## Handoff Requirements
|
|
- Record DOF and reaction foundation status in `PROGRESS.md`.
|
|
|
|
## Do Not
|
|
- Do not bypass `DofManager` from elements or analysis code.
