Michael Sprague focused on enhancing the Exawind/openturbine repository by delivering a series of in-depth documentation and theoretical modeling improvements over six months. He consolidated and expanded user-facing and technical documentation using Sphinx and reStructuredText, standardizing notation and clarifying complex topics such as beam theory, damping terms, and benchmarking procedures. His work included updating the README for onboarding, aligning theoretical content with code implementations, and improving reproducibility through detailed benchmark documentation. By leveraging Python and technical writing skills, Michael addressed both onboarding and model fidelity challenges, resulting in more accessible, accurate, and maintainable documentation that supports cross-team collaboration and future development.

December 2025 (2025-12) — Exawind/openturbine: Documentation-focused sprint delivering damping-term accuracy fixes and onboarding enhancements. Corrected damping term representations and notational issues in the D2 model, added missing transposes, and fixed K^D1 term reference (D_22 -> D_21). Expanded README with comprehensive overview of Kynema and its CFD integration, improving onboarding and integration readiness. Overall impact: higher model fidelity, reproducibility, and faster adopter ramp-up; demonstrates rigorous documentation discipline and cross-codebase consistency.
