My structure consists of a 2D array of air holes in a silicon background, with a lattice constant of 500 nm. I'm using a Gaussian source with a wavelength range of 1500-1600 nm. I've meshed the structure with a maximum mesh size of 20 nm. lumerical forum

Since the acquisition, the forum has become more integrated with the broader Ansys ecosystem (including HFSS, Q3D Extractor, and Mechanical). Recent updates include a unified login with the Ansys Customer Portal and better support for multiphysics coupling. Expect to see deeper AI-assisted search within the forum—allowing you to ask natural language questions like, “How do I model a graphene-based modulator in FDTD?” and receive curated threads as answers. on how to post a question for the best response

While the community is peer-driven, Ansys application engineers frequently chime in. This ensures that the advice provided aligns with the latest software updates and best practices. 4. Application-Specific Galleries I've meshed the structure with a maximum mesh size of 20 nm

Hope this helps!
