So next time your simulation diverges into infinity or your optical mode looks like static on a TV, take a deep breath. Take a screenshot. And go post it on the Lumerical Forum.
Why? Because photonics is hard. Unlike circuit simulation, where "ground" is a safe assumption, in FDTD (Finite-Difference Time-Domain) solutions, everything is boundary conditions and mesh order. lumerical forum
For thousands of engineers and researchers, the answer is not a dusty textbook or a lonely help file. It is the . The "Rubber Duck" for Nanophotonics Software forums often devolve into graveyards of unanswered questions. The Lumerical Forum, however, has evolved into something rare: a genuinely warm, high-signal-to-noise community. So next time your simulation diverges into infinity
