Shell Surface Pressure Load Coordination Record

1. Metadata and Feature Scope

• feature_id: shell-surface-pressure-load
• workflow_state: needs-implementation
• owner_agent: coordinator-agent
• request_date: 2026-08-30
• last_updated: 2026-08-31
• process_classification: architectural
• current_goal: 승인·감사된 Harness Step 1–7을 한 Implementation Agent/Executor 흐름으로 순차 실행하고 Gate 6 implementation/build/reference evidence를 확보한다.
• approved_scope: Abaqus subset *SURFACE, TYPE=ELEMENT와 *DSLOAD의 uniform P를 S4/S4R SPOS|SNEG surface에 적용한다. Linear static은 reference configuration load를, nonlinear static은 current-configuration follower load와 external tangent를 사용한다.
• scope_boundaries: Unsupported surface/load variants는 fail-closed로 거부하고 stable source identity와 deterministic load/reduction order를 보존한다. 기존 authoritative HDF5 output을 우선 유지하되 Stage 5 I/O gate가 evidence로 최종 확정한다.
• reference_case: reference/shellNL-meshfine-pressure/의 existing .inp와 CSV를 exact path/name 그대로 read-only 사용한다.
• user_approval: 2026-08-30 approved Abaqus-aligned design; 2026-09-01 approved the 7-Step implementation plan, phase materialization, and Harness implementation/verification execution without push.

• critical_user_questions: 없음
• USER-DECISION-001: resolved 2026-09-01; 7-Step draft, phase materialization, Harness implementation/verification execution 승인. --push는 승인되지 않음.
• RISK-001: Element-based *DLOAD pressure와 surface-based *DSLOAD pressure의 sign/target 의미를 혼합하지 않는다.
• RISK-002: Nonlinear follower pressure의 current-surface force와 external tangent를 fixed-global *CLOAD와 혼합하지 않는다.
• RISK-003: Reference artifact 또는 공통 tolerance를 기능 통과를 위해 수정하지 않는다.
