Usage guide / 使用指南
Files and task identity / 文件与任务标识
Files follow <track>_<content>.json: extended_cases.json, extended_reference_qois.json, extended_measurement_specs.json, extended_qoi_design.json, and extended_evidence_contract.json. Basic/Advanced use the same case/reference naming. OpenFOAM Foundation 13 compatibility is recorded in release metadata; schema versions stay inside their documents. / 文件统一采用“任务组 + 内容”命名，OpenFOAM 版本写入发布元数据，格式版本保留在文件内容中。
data/extended.jsonl is the 100-task ExtFoamBench catalog. Each row has task_id, track, case_id, family, task_origin, usr_requirement, and external_asset_ids. Use (track, case_id) to join task records to the cases mappings in reference-QoI and numerical-statistics JSON files. Basic/Advanced catalogs follow the same format and retain upstream attribution.
data/extended.jsonl 是 100 条 Ext 原创任务的索引，包含上述字段。使用 (track, case_id) 与参考 QoI、数值统计中的 cases 条目对应；Basic/Advanced 采用相同格式，并注明上游来源。
Reference input JSONs contain OpenFOAM file text, such as 0/U, system/controlDict and Allrun; some Extended tasks have reference_subcases. Geometry declarations resolve through benchmarks/assets/manifest.json. Keep reference inputs and answers outside the solving agent's accessible workspace.
参考输入 JSON 保存 OpenFOAM 文件内容，部分 Ext 任务还包含多个参考分支。几何声明通过资产清单关联文件。参考输入与答案应置于求解智能体无法读取的位置。
Reference data use reference/<track>/... as portable provenance labels, not bundled raw-run directories. The original labels are traceable through the source manifest. / 参考数据中的 reference/<track>/... 是可移植的来源标识，不代表包内包含原始运行目录；原始记录可通过来源清单追溯。
Optional evaluator / 可选评估器
The scorer, schemas and scripts are bundled in tools/evaluation-tools.zip. Extract it into the downloaded repository root, preserving its paths. Use Python 3.11/3.12 and a dedicated evaluator environment; current HF datasets dependencies may require a different NumPy version.
评估器、格式定义和脚本集中在工具包中。请将其解压到下载的仓库根目录，保留相对路径。使用 Python 3.11/3.12 和独立评估环境，避免与最新 HF 数据加载依赖的 NumPy 版本冲突。
python -m zipfile -e tools/evaluation-tools.zip .
python -m pip install -r requirements.txt
python -m benchmarks.evaluation validate-profile --profile benchmarks/evaluation/profiles/extended.json
python examples/inspect_task.py --track extended --case-id nozzleCDV/1
These commands inspect data without running a model or CFD solver. The inspection output includes evaluator-side information; it is not an agent prompt.
上述命令只检查数据，不调用模型或 CFD 求解器。任务查看命令包含评价侧信息，不应直接作为智能体提示词。
To export one reference input without solving it / 导出一个参考算例输入：
python benchmarks/scripts/materialize_benchmark.py --benchmark benchmarks/extended_cases.json --case-id nozzleCDV/1 --output-root outputs/reference-input
To evaluate an existing compatible run, replace /path/to/run with your retained artifacts / 评价已有运行结果时，将路径换成实际结果目录：
python -m benchmarks.evaluation evaluate --profile benchmarks/evaluation/profiles/extended.json --adapter easyfoam --run-root /path/to/run --output outputs/evaluation
Other adapters: foamagent, chatcfd, coding-agent. Their required layouts are defined in the extracted benchmarks/evaluation/adapters/. Full-profile evaluation counts missing tasks as failures; a single-task run does not reproduce a full-benchmark score.
其他适配器支持上述三种布局，具体输入结构见解压后的目录。完整配置会将未运行任务计为失败，单任务运行不代表完整基准成绩。
Metric fields and protocol / 指标字段与协议
| Metric / 指标 | Field under overall / 汇总字段 |
|---|---|
| ECR | execution_pass_rate |
| Numerical acceptance / 数值接受率 | numerical_pass_rate_all_tasks |
| QoI acceptance / 物理接受率 | physics_grounded_qoi_pass_rate_all_tasks |
| TAR | end_to_end_pass_rate |
Rates use all assigned tasks and range from 0 to 1. Execution gates Numerical/QoI acceptance; all mandatory criteria must pass. Conditional rates and partial-quality scores are supplementary. The Extended rules retain their declared provisional tolerance status. For Basic/Advanced, the mandatory set combines physical scalar criteria with a family-specific spatial response profile. The exact required metrics are listed in each reference record's principal_metrics; other histories, profiles and feature locations remain diagnostic. Spatial coverage counts profile-field combinations; early-convergence markers can satisfy the stop condition.
上述比例均以全部指定任务为分母，范围为 0–1。数值和物理接受以执行通过为前提，所有必需准则均需通过；条件通过率和部分质量分数属于辅助信息。Ext 保留原有 provisional 容差状态。Basic/Advanced 的必需指标同时包含物理标量准则与家族对应的空间响应曲线，具体以每个参考条目的 principal_metrics 为准；其他历史、曲线与特征位置属于诊断信息。空间覆盖按曲线与场的组合统计，执行终止条件允许提前收敛标记。
Actual simulations require OpenFOAM Foundation 13. Offline extraction uses retained data, but some missing measurement fields or topology-changing geometries require native foamPostProcess. --prepare writes derived fields; --check-mesh enables a fresh mesh audit. Use copies of valuable run artifacts when preparing measurements.
真实仿真需要 OpenFOAM Foundation 13。离线提取通常读取留存数据，但部分测量场或拓扑变化几何需要原生后处理工具。--prepare 会写入派生场，--check-mesh 可启动网格检查；处理重要运行结果时建议使用副本。
Coverage, provenance and versions / 覆盖、来源与版本
