OpenTurbine development began in 2023, is ongoing, and we aim for beta release in 2025
OpenTurbine is an open-source flexible-multibody-dynamics simulation code designed to meet the research needs of Wind Energy Technologies Office (WETO) and the broader wind energy community for land-based and offshore wind turbines. OpenTurbine provides high-fidelity, highly performant structural dynamics models that can couple with low-fidelity aerodynamic/hydrodynamic models like those in OpenFAST, as well as high-fidelity computational fluid dynamics (CFD) models like those in the WETO and Office of Science supported ExaWind code suite.
The following describes the high-level development objectives conceived for OpenTurbine:
- OpenTurbine will follow modern software development best practices, including test-driven development (TDD), version control, hierarchical automated testing, and continuous integration (CI) for a robust development environment.
- The core data structures are memory efficient and enable vectorization and parallelization at multiple levels.
- Data structures are data-oriented to exploit methods for accelerated computing including high utilization of chip resources (e.g., single instruction multiple data (SIMD) instruction sets) and parallelization using GP-GPUs.
- The computational algorithms incorporate robust open-source libraries for mathematical operations, resource allocation, and data management.
- The API design considers multiple stakeholder needs and ensure integration with existing and future ecosystems for data science, machine learning, and AI.
- OpenTurbine is written in modern C++ and leverages Kokkos as its performance-portability library with inspiration from the ExaWind stack.
OpenTurbine is primarily developed with the support of the U.S. Department of Energy (DOE) and is part of the WETO Software Stack. For more information and other integrated modeling software, see:
Support was also provided by the DOE Office of Science FLOWMAS Energy Earthshot Research Center.
