LumericalFDTD SKILL.md skillA
LumericalFDTD from lex669/lumericalfdtd-skill is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add lex669/lumericalfdtd-skill/LumericalFDTD@git:20260907.8d67aa1Pins git:20260907.8d67aa1 in mdr.lock. Pin the fingerprint instead.

端到端 Ansys Lumerical FDTD 仿真自动化 — 从零构建模型、运行仿真、自动debug、数据分析与可视化全流程。当你需要完整的光学仿真项目（建模→仿真→分析→验收）时使用此skill。 End-to-end Ansys Lumerical FDTD simulation automation — full pipeline from modeling through simulation to analysis and verification. Use when you need a complete photonics simulation project. 子技能（单独使用某个阶段）：建模用 LumericalFDTD-modeling / 仿真执行用 LumericalFDTD-simulation / 数据分析用 LumericalFDTD-analysis.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Lumerical FDTD 全流程仿真
## 核心工作流（必须严格按顺序执行，不可跳过）
每次处理完整 FDTD 任务时严格遵循以下三阶段流水线。**创建文件只是准备阶段，运行仿真才是核心工作。**
### 阶段 A：准备与建模
1. **理解需求** — 确认器件结构（几何参数、材料）、光源（波长范围、偏振）、监视器要求、验收条件
2. **环境探测**（本会话首次时）— 定位 Lumerical Python 解释器路径
3. **编写 `*_sim.py`** — 生成仿真脚本，包含结构构建、光源、监视器、`fdtd.run()`、数据保存
> 仅需建模不跑仿真 → 改用 `LumericalFDTD-modeling` skill
### 阶段 B：执行仿真（不可跳过，不可省略）
4. **运行仿真脚本** — 用 Bash 工具调用 Lumerical Python 解释器执行 `*_sim.py`
5. **检查输出** — 确认 `.fsp` 和 `.npz` 文件已生成，检查日志无致命错误
6. **如遇错误** — 读取 `references/common-errors.md`，修复脚本，回到步骤 4。**最多重试 5 次**，超过则向用户报告所有尝试过的修复及错误，请求人工介入
7. **编写并运行 `*_analysis.py`** — 读取 `.npz` 数据，计算指标，绘图保存 `.png` 到**新建的 `pic/<label>_run_<NN>/` 子目录**（归档约定见「文件管理规则」；辅助函数 `new_run_dir` 见 `LumericalFDTD-analysis` skill 模板，只写入 `*_analysis.py`，不写入 `*_sim.py`）
> 仅需分析已有数据 → 改用 `LumericalFDTD-analysis` skill
### 阶段 C：验收
8. **验证结果** — 进入**最新 run 子目录**（`NN` 最大者）检查其中的 `.png` 图表是否满足验收条件（透射率、模式分布、衍射环等），不满足则调整 `*_sim.py` 参数回到步骤 4
9. **更新 REPORT.md** — 记录仿真参数、结果摘要、图表说明，并注明本次图表的 run 目录路径（如 `pic/glass_gaussian_run_02/`）
### 错误处理循环（含最大重试上限）
```
重试次数 = 0
最大重试 = 5
while 仿真未成功 and 重试次数 < 最大重试:
运行 sim.py
if 报错:
读取 references/common-errors.md
根据错误类型定位解决方案

How to install
mdr add lex669/lumericalfdtd-skill/LumericalFDTD@sha256:ed42bf1ff9c5c16aThe line at the top of this page pins the label git:20260907.8d67aa1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
