# Step 2: element-base-interface
|
|
|
|
## Read First
|
|
|
|
Read these files before editing:
|
|
|
|
- `/AGENTS.md`
|
|
- `/docs/AGENT_RULES.md`
|
|
- `/docs/ARCHITECTURE.md`
|
|
- `/docs/implementation-plans/analysis-model-objects-implementation-plan.md`
|
|
- `/include/fesa/core/ElementDefinition.hpp`
|
|
- `/CMakeLists.txt`
|
|
|
|
## Task
|
|
|
|
Add the abstract element model interface.
|
|
|
|
Allowed files:
|
|
|
|
- Create `/include/fesa/element/Element.hpp`
|
|
- Create `/tests/element/element_base_test.cpp`
|
|
- Modify `/tests/core/domain_bootstrap_test.cpp` only if the current test executable remains the single test runner
|
|
- Modify `/CMakeLists.txt`
|
|
|
|
Required interface:
|
|
|
|
- virtual destructor.
|
|
- `ElementId id() const noexcept`.
|
|
- `ElementType type() const noexcept`.
|
|
- `std::size_t nodeCount() const noexcept`.
|
|
- `std::span` is not allowed because this project targets C++17.
|
|
- Use const reference return for connectivity data.
|
|
- no stiffness, residual, stress, state, or equation API in this phase.
|
|
|
|
## Tests To Write First
|
|
|
|
Write `/tests/element/element_base_test.cpp` before production changes. Use a small test subclass to prove:
|
|
|
|
- base pointer dispatch works.
|
|
- id/type/connectivity/property id are readable through base API.
|
|
- deleting through `std::unique_ptr<Element>` is valid.
|
|
|
|
Run targeted build and confirm RED because `Element.hpp` is missing.
|
|
|
|
## Acceptance Criteria
|
|
|
|
Run:
|
|
|
|
```powershell
|
|
python scripts/validate_workspace.py
|
|
ctest --test-dir build/msvc-debug --output-on-failure -C Debug -R model-object
|
|
```
|
|
|
|
Update step 2 status.
|
|
|
|
## Do Not
|
|
|
|
- Do not implement MITC4 stiffness or numerical element behavior.
