About FDTD

使用lumerical-fdtd进行photonic-crystal仿真

About Python API

Use Python to analyze data, automate complex workflows\optimizations, and produce publication-quality plots. The Ansys Lumerical Python APIs provides a method to seamlessly use Python to interact with Ansys Lumerical products.

Python API overview – Ansys Optics Lumerical Python API Reference – Ansys Optics

Get Start

First, ensure you have installed Ansys Optics (Lumerical). Then include the api path to your environment variable. A simple method is dynamic add path in python.

import sys
sys.path.append(r"C:\Program Files\Lumerical\v242\api\python")
import lumapi

For example, we want to use FDTD,

model = lumapi.FDTD(hide=False) # open session of FDTD, not hide GUI
fdtd = model.addfdtd() # add fdtd simulation domain
# fdtd = model.getObjectById('FDTD') # get FDTD object by ID.

Notes

• The unit in script is SI unit (m, s, etc.).
• The properties name has space need to be replaced with underscore _. e.g. fdtd.x_span.
