Assumptions & limits

Assumptions & limits

  • Wave height, fluid density, gravity, convention. Returns Mean ideal energy per area. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Wave height (m): minimum 0, maximum 1000000000000.0. Fluid density (kg/m³): minimum 1e-12, maximum 1000000000000.0. Gravity (m/s²): minimum 1e-12, maximum 1000000000000.0. Height convention: 0 regular-wave H; 1 spectral significant Hm0: minimum 0, maximum 1.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
