LumericalFDTD-analysis SKILL.md skillA
LumericalFDTD-analysis 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-analysis@git:20260907.8d67aa1Pins git:20260907.8d67aa1 in mdr.lock. Pin the fingerprint instead.

分析 Ansys Lumerical FDTD 仿真结果 — 读取.npz数据、计算光学指标、生成发表级图表。当你需要分析FDTD结果、绘制场分布图、计算透射率/衍射效率时使用此skill。 Analyze Ansys Lumerical FDTD simulation results — load .npz data, compute optical metrics, generate publication-quality figures. Use when analyzing FDTD results, plotting field distributions, computing transmission/diffraction efficiency.
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
# FDTD 数据分析器
## 职责范围
本 skill **仅负责**数据分析与可视化阶段：读取 `.npz` 数据、计算光学指标、绘制图表、验证验收条件。输出 `.png` 图表文件。
**不负责**：结构建模（→ `LumericalFDTD-modeling`）、仿真执行（→ `LumericalFDTD-simulation`）、端到端全流程（→ `LumericalFDTD`）。
## 前置条件
`.npz` 数据文件必须已存在于 `data/` 目录。若不存在，先运行仿真。
## 工作流
### 1. 确认数据可用
```bash
ls path/to/project/data/
# 确认 results.npz 等文件存在
```
### 2. 编写分析脚本
按模板生成 `*_analysis.py`（纯数据分析，不调 `lumapi.FDTD`）。
> **每次运行分析脚本必须新建独立的 run 子目录保存图表（`pic/<label>_run_<NN>/`），禁止直接写入 `pic/` 根目录**。下方模板内嵌的 `new_run_dir()` 辅助函数及调用**必须完整保留**，不得删除或改写；`label` 需按本次仿真内容填写（规则见「图表归档约定」）。
```python
import os
import glob
import numpy as np
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
def new_run_dir(pic_dir, label):
"""本次运行的图表目录 pic/<label>_run_<NN>（NN 自动递增，从 01 起补零）"""
n = 0
for d in glob.glob(os.path.join(pic_dir, label + "_run_*")):
suffix = os.path.basename(d)[len(label) + 5:] # 去掉 "<label>_run_" 前缀
if suffix.isdigit():
n = max(n, int(suffix))
run_dir = os.path.join(pic_dir, f"{label}_run_{n + 1:02d}")
os.makedirs(run_dir, exist_ok=True)
return run_dir
# label = 本次仿真内容的 1-3 个区分关键词（snake_case，如 glass_gaussian / si_planewave_1550nm）

How to install
mdr add lex669/lumericalfdtd-skill/LumericalFDTD-analysis@sha256:0f82c0e7f9fbc68aThe 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.
