VIVyD: an open-source initiative toward a unified framework for VIV modeling

This work introduces VIVyD, an open-source Python framework for the unified modeling and analysis of vortex-induced vibrations (VIV). The platform is designed to overcome the fragmentation of existing approaches by providing a modular and extensible environment integrating models, solvers, stochastic forcing, datasets, and post-processing tools. VIV models are implemented as standardized, object-oriented components, enabling consistent comparison and straightforward extension. The framework supports time-domain simulations and facilitates re-producible evaluation against reference datasets. Distributed via PyPI and developed collaboratively on GitLab, VIVyD aims to serve both the scientific and industrial communities. By promoting transparency, reproducibility, and community contributions, the project seeks to establish a robust foundation for the development, validation, and application of VIV models.
