If you are just starting, look for resources that guide you through your first simulation. The section in the official FDTD course is an excellent starting point for a beginner with detailed guidance, forming a great getting-started tutorial. Following this, the video lesson "Setting Up the Simulation in Ansys Lumerical FDTD" is highly recommended for hands-on learners, as it demonstrates constructing a nanohole array simulation from scratch. Similarly, the "Building and Simulating Waveguides" lesson provides a practical, project-based tutorial on designing a silicon waveguide, showing exactly how to set up the solver, add sources, place monitors, and configure boundary conditions.
Professional designers often import layout files directly from CAD tools.
While there is no single official "Lumerical FDTD Tutorial PDF" from the developer, the core documentation and learning paths are hosted on the Ansys Optics Discovery Forum and the Ansys Learning Hub . lumerical fdtd tutorial pdf
Ansys Lumerical FDTD (Finite-Difference Time-Domain) is the industry-standard software for simulating light interaction with sub-wavelength structures. Engineers and researchers use it to design metasurfaces, silicon photonics, solar cells, and micro-LEDs.
Your journey to mastering Lumerical FDTD is a progression from understanding core concepts to tackling advanced research problems. While the community-shared PDFs remain a valuable starting point for many, especially for translated documentation and quick references, the most comprehensive and up-to-date learning path is now officially provided by Ansys. If you are just starting, look for resources
import sys # Append the Lumerical API path (adjust based on OS and version) sys.path.append("C:\\Program Files\\Ansys Inc\\v261\\v261\\api\\python\\") import lumapi # Launch FDTD with lumapi.FDTD() as fdtd: fdtd.eval("newproject;") fdtd.addrectangle(name="nano_disk", r=0.2e-6, z_span=0.1e-6) fdtd.set("material", "TiO2 - Siefke") fdtd.save("python_autosave.fsp") Use code with caution. 5.
