|

|

The findings below captured the pre-correction state after the initial step 7 implementation. The follow-up correction in `docs/corrections/uel-3d-euler-beam-uel-abi-correction.md` adds the missing Abaqus-callable wrapper, changes the Abaqus-facing state-variable policy to `NSVARS>=1` / `VARIABLES=1`, and adds `LFLAGS(1)` and `LFLAGS(4)` validation.

- Abaqus/Standard가 실제로 호출하는 `UEL` subroutine의 positional ABI는 무엇인가?
|

Post-step ABI correction note: the original step 7 implementation deliberately deferred the fixed-form Abaqus `UEL` wrapper. The follow-up correction report `docs/corrections/uel-3d-euler-beam-uel-abi-correction.md` supersedes that deferred-wrapper status and records the added wrapper, `NSVARS>=1` policy, and `LFLAGS(1)/(4)` checks.

|

- first_failed_command: `python -m unittest scripts.test_uel_3d_euler_beam_uel`; `python scripts/validate_fortran.py`
|
||||
- failed_target_or_test: missing Abaqus `UEL` wrapper; adapter rejected `NSVARS=1`
|
||||
- evidence_tail: wrapper source-smoke failed because `src/fortran/uel_3d_euler_beam_uel.for` was missing; Fortran ABI test failed with `actual=6 expected=0` for a valid `NSVARS=1` static call
|
||||
- triage_decision: implementation-owned correction allowed after research clarified the Abaqus manual ABI
|
||||
|
||||
## Root Cause Summary
|
||||
- root_cause_type: implementation boundary defect and stale interface policy
|
||||
- summary: the step 7 code implemented a testable kernel and no-Abaqus adapter, but did not expose the top-level Abaqus `SUBROUTINE UEL(...)`. The adapter also kept the pre-research `NSVARS=0` policy, conflicting with the documented `*USER ELEMENT, VARIABLES` requirement for a positive allocation.
|
||||
- why_minimal_fix_is_allowed: the correction preserves the existing kernel formulation and only fixes the Abaqus-facing call boundary, state-variable allocation check, and static-procedure `LFLAGS` validation.
