VANE documentation
VANE — Visualization and Automated Natural-frequency Extraction — is a Python library for automated OpenFAST linearization post-processing, physics-aware mode identification, and digital-twin-ready state-space export for fixed-bottom and floating offshore wind turbines.
Note
VANE is in alpha. The public API may change before the first tagged release.
VANE turns a set of OpenFAST linearization (.lin) files into identified,
labelled, uncertainty-aware modes, a Campbell diagram with resonance crossings, and a
clean state-space model ready for a Kalman-filter digital twin — in a few lines of
code, with validation against analytical and reference solutions.
