Welcome, and thank you for helping test nl2ocean

nl2ocean turns a plain-English description of a coastal ocean simulation into a ready-to-run Oceananigans.jl script. A small language model reads your description and fills in the simulation settings; the code itself comes from fixed templates. We want to know how well it understands oceanographers.

Each test takes 2–3 minutes:

1. Describe a simulation you might actually set up, in your own words.
2. Write down what you expect the tool to produce: the key settings, as you understand your own request.
3. Run it, compare, press Wrong on any setting it got wrong, rate it, and submit.

What it can represent today: 2D (x–z) or 3D boxes; flat, sloping or bump (sandbar/reef) seafloors; no / linear / two-layer stratification; tidal currents, steady currents, wind, surface heat flux, Coriolis; suspended sediment that settles; vegetation drag (marsh, seagrass, kelp). Requests outside this are welcome too, since telling us what's missing is useful.

What we collect: your descriptions, expected outputs, ratings and comments, along with the name on your invitation. Only the study organizer sees them. The tool runs on a single computer, so if someone else is testing at the same time you may wait a few seconds.
