hf-dataset-publishing

Save/publish analysis or computation results from ANY ecosystem repo to Hugging Face as a queryable, viewer-renderable dataset. Use when the user wants to "save results to hugging face", "publish dataset to HF", "hugging face data saving", "save analysis results", "hf dataset", "make results queryable", or "render via datasets-server API". Reshapes nested results into flat parquet tables, writes a dataset card with a viewer `configs:` block and provenance, applies license/public-vs-private routing, enforces a domain data-quality gate (faithful-to-source != correct), publishes to `aceengineer/<repo>-<projection>`, and verifies via the datasets-server API.

Orcaflex Operability

When to Use

Operability envelope generation for mooring systems

Weather downtime calculations from scatter diagrams

Critical heading identification for design loads

Multi-sea-state analysis (1yr, 10yr, 100yr return periods)

Tension limit assessment (intact vs damaged conditions)

Annual operational availability studies

Polar coordinate visualization of system limits

Prerequisites

OrcaFlex simulation results (.sim files) for multiple headings

Wave scatter diagram (Hs-Tp probability matrix)

Python environment with digitalmodel package installed

Tension limits for intact and damaged conditions

Python API
