## 작업
|
|
|
|
1. `MITC4-GEO-001..004`를 먼저 작성하고 CMake에 test source를 등록한다.
|
|
2. Backend-neutral model geometry module에 element normal candidate, deterministic
|
|
area-weighted nodal director, pairwise positive orientation, right-handed nodal
|
|
tangent frame with documented axis tie-break, structured validation seam을 만든다.
|
|
3. Center, eight stiffness points, four tying points, four committed recovery points에서
|
|
finite bases, nonzero surface measure, positive finite Jacobian을 검사한다.
|
|
4. Valid planar/rotated/warped cases와 duplicate, bow-tie, zero-area, reversed,
|
|
nonfinite, nonpositive-J, opposed-normal cases를 검증한다.
|
|
|
|
## Acceptance Criteria
|
|
|
|
```powershell
|
|
$requiredBuildPaths=@("C:/git/googletest","C:/Program Files (x86)/Intel/oneAPI/mkl/2026.1/lib/cmake/mkl","C:/Program Files (x86)/Intel/oneAPI/tbb/2023.1/lib/cmake/tbb","C:/Program Files/HDF_Group/HDF5/2.1.1/cmake")
|
|
foreach($p in $requiredBuildPaths){if(-not(Test-Path -LiteralPath $p)){throw "Missing $p"}}
|
|
cmake --fresh -S . -B .harness/build -G "Visual Studio 18 2026" -A x64 `
|
|
"-DFESA_GTEST_SOURCE_DIR=C:/git/googletest" `
|
|
"-DMKL_DIR=C:/Program Files (x86)/Intel/oneAPI/mkl/2026.1/lib/cmake/mkl" `
|
|
"-DTBB_DIR=C:/Program Files (x86)/Intel/oneAPI/tbb/2023.1/lib/cmake/tbb" `
|
|
"-DHDF5_DIR=C:/Program Files/HDF_Group/HDF5/2.1.1/cmake"
|
|
cmake --build .harness/build --config Debug --target fesa_unit_tests
|
|
ctest --test-dir .harness/build -C Debug -R "Mitc4Geometry" --output-on-failure
|
|
```
|
|
|
|
Expected missing geometry API/behavior RED를 확인한 뒤 minimal GREEN. 이후:
|
|
|
|
```powershell
|
|
cmake --build .harness/build --config Debug --target fesa_unit_tests
|
|
ctest --test-dir .harness/build -C Debug -R "Mitc4Geometry|DomainModel|InpDomainMapping" --output-on-failure
|
|
cmake --build .harness/build --config Debug
|
|
ctest --test-dir .harness/build -C Debug --show-only=json-v1
|
|
ctest --test-dir .harness/build -C Debug --output-on-failure
|
|
```
|
|
|
|
## 검증 및 상태 갱신
|
|
|
|
RED/VERIFY evidence를 summary에 남기고 현재 Step 상태만 갱신한다. Executor-owned
|
|
timestamp/retry/commit/advancement를 쓰지 않는다.
|
|
|
|
## 금지사항
|
|
|
|
- Calibrated smooth angle, warp/distortion threshold, NR-O03/NR-O04를 추가하지 마라.
|
|
- Parser keyword policy나 element stiffness를 구현하지 마라.
|
|
- Invalid geometry를 clamp/repair하지 마라.
|
|
- Reference/upstream 문서를 수정하거나 직접 commit/hook 실행을 하지 마라.
