Project and community#
FDTDX is open-source research software. This fork’s contribution is a transparent path from solver implementation to evidence: cases, tolerances, provenance, and known limits are kept together.
Every live and archived optimization in one image-first directory. Each card pairs the actual geometry with its electric-field profile.
All nanobeam, remote-atom, curved-mirror, atom-gap, beta-first, and SiN cavity campaigns are collected in one section, including frozen results, failed attempts, validation records, geometries, and fields.
What passes today, what is blocked, and what those labels actually mean.
Goldens, resolution-aware metrics, inverse-design parity, and anti-cheating rules.
Why former green FOMs were withdrawn, exact notebook discrepancies, symmetry normalization, and GPU memory evidence.
Strong areas and the work needed to approach broad Tidy3D-like FDTD coverage.
Develop the solver, add a case, improve docs, or reproduce an existing result.
Credit upstream FDTDX and identify the validation fork in reproducible work.
