FDTD是一种仿真算法，适用于处理波长尺度下的光学/光子学体系，原理是对 麦克斯韦方程组 的差分化处理，之后的FDTD特指 Lumerical 的FDTD仿真软件。 python用于调用FDTD中的材料、结构以进行建模，调用仿真引擎进行计算，存取仿真数据进行分析。 在我快要离开这个领域的时候，FDTD已经开始支持GPU加速，在网上如MSDN可以下载到相应的破解版本，用消费级GPU即可获得相比服务器级别CPU 5x左右的计算效率，请大家注意。 以 pycharm 为例，在新建project …

This module is a part of the pyOMA2 package and provides utility functions for conducting Operational Modal Analysis (OMA) using Frequency Domain Decomposition (FDD) algorithm [BZA01], Enhanced Frequency Domain Decomposition (EFDD) algorithm [BVA01] and Frequency Spatial Domain Decomposition (FSDD) algorithm [ZWT10].

Frequency Domain Decomposition (FDD) algorithm for operational modal analysis. This class implements the FDD algorithm, used to identify modal parameters such as natural frequencies, damping ratios, and mode shapes from ambient vibrations.

open-fdd is an open-source Fault Detection and Diagnostics (FDD) tool designed for analysts and engineers using local toolsets like Jupyter notebooks. It is not necessarily an IoT tool for Grafana, which an MSI (Master Systems Integrator) might use, though it could be adapted for that purpose.
