| # digitalmodel — Parametric Atlas Explorer |
|
|
| Pre-computed parametric result grids from **digitalmodel**, each generated from standard-traceable engineering code and validated against a held-out sample. Every config is a synthetic parametric sweep — no client or project-specific data. |
|
|
| These power the live capability pages on [aceengineer.com/capabilities](https://www.aceengineer.com/capabilities/). |
|
|
| ## Configs |
|
|
| ### `mooring_fatigue` |
| |
| Chain/steel mooring fatigue damage (S-N) across stress range, cycle count, and DNV S-N curve class. |
| |
| - **Standard:** DNV-RP-C203 (2021-09) |
| - **Response:** `damage` · **Rows:** 312 · **Columns:** `stress_MPa`, `n_cycles`, `sn_curve`, `damage` |
| - **Validation:** max_rel_error = 0.07427 (threshold 0.1, PASS) |
|
|
| ### `synthetic_rope_mooring_fatigue` |
| |
| Synthetic-rope mooring fatigue damage (T-N) across tension range, cycle count, and minimum breaking load. |
| |
| - **Standard:** DNV-OS-E301 (2018-07) |
| - **Response:** `damage` · **Rows:** 120 · **Columns:** `tension_range_kN`, `n_cycles`, `MBL_kN`, `damage` |
| - **Validation:** max_rel_error = 8.353e-15 (threshold 0.1, PASS) |
| |
| ### `code_check` |
|
|
| Riser/pipe code-check utilisation across outer diameter, wall thickness, tension, bending moment, and steel grade. |
|
|
| - **Standard:** API-RP-2RD (2013) |
| - **Response:** `utilisation` · **Rows:** 2,700 · **Columns:** `outer_diameter`, `wall_thickness`, `effective_tension_kN`, `bending_moment_kNm`, `smys`, `utilisation` |
| - **Validation:** max_rel_error = 0.06073 (threshold 0.1, PASS) |
|
|
| ## Provenance & limits |
|
|
| Each config is a deterministic sweep over the axes in its `manifest.yaml` (uploaded alongside the data). Values are model outputs from the cited standard's formulation, intended for screening and capability demonstration — not a substitute for a project-specific engineering check.
