The MODE reference manual provides detailed descriptions of product and solver (FDE, EME, varFDTD) features.
- FDE, EME, varFDTD courses: Self-paced courses intended for beginner to intermediate users with a focus on providing an understanding of solver physics, simulation workflow and data analysis. The "My first simulation" section is a great getting-started tutorial.
- Ansys Learning Forum (Photonics category): A large repository of Q&A content from the Ansys Lumerical community.
- Application Gallery: Find example files, simulation methodologies, and tips to help you get started quickly and easily. You can also browse the application gallery directly from within our products. Waveguides and Edge Couplers are good examples to start with.
