Nalu-Wind

Documentation | Nightly test dashboard

Nalu-Wind is a generalized, unstructured, massively parallel, incompressible flow solver for wind turbine and wind farm simulations. The codebase is a wind-focused fork of NaluCFD; NaluCFD is developed and maintained by Sandia National Laboratories. Nalu-Wind is being actively developed and maintained by a dedicated, multi-institutional team from National Renewable Energy Laboratory, Sandia National Laboratories, and Univ. of Texas Austin.

Nalu-Wind is developed as an open-source code with the following objectives:

  • an open, well-documented implementation of the state-of-the-art computational models for modeling wind farm flow physics at various fidelities that are backed by a comprehensive verification and validation (V&V) process;

  • be capable of performing the highest-fidelity simulations of flowfields within wind farms; and

  • be able to leverage the high-performance leadership class computating facilities available at DOE national laboratories.

We hope that this community developed model will be used by research laboratories, academia, and industry to develop the next-generation of wind farm technologies. We welcome the wind energy community to use Nalu-Wind in their research. When disseminating technical work that includes Nalu-Wind simulations please reference the following citation:

Part of the WETO Stack

Nalu-Wind is primarily developed with the support of the U.S. Department of Energy and is part of the WETO Software Stack. For more information and other integrated modeling software, see: - Portfolio Overview - Entry Guide - High-Fidelity Modeling Workshop

Documentation

Documentation is available online at https://exawind.github.io/nalu-wind/ and is split into the following sections:

  • Theory manual: This section provides a detailed overview of the supported equation sets, the discretization and time-integration schemes, turbulence models available, etc.

  • Verification manual: This section documents the results from verification studies of the spatial and temporal schemes available in Nalu-Wind.

  • User manual: The user manual contains detailed instructions on building the code, along with the required third-party libraries (TPLs) and usage.

All documentation is maintained alongside the source code within the git repository and automatically deployed to a github-hosted website upon new commits.

Compilation and usage

Nalu-Wind is primarily built upon the packages provided by the Trilinos project, which in turn depends on several third-party libraries (MPI, HDF5, NetCDF, parallel NetCDF), and YAML-CPP. In addition, it has the following optional dependencies: hypre, TIOGA, and OpenFAST. Detailed build instructions are available in the user manual. We recommend using Spack package manager to install Nalu-Wind on your system.

Testing and quality assurance

Nalu-Wind comes with a comprehensive unit test and regression test suite that exercise almost all major components of the code. The master branch is compiled and run through a regression test suite with different compilers (GCC, LLVM/Clang, and Intel) on Linux and MacOS operating systems, against both the master and develop branches of Trilinos. Tests are performed both using flat MPI and hybrid MPI-GPU hardware configurations. The results of the nightly testing are publicly available on CDash dashboard.

Contributing, reporting bugs, and requesting help

To report issues or bugs please create a new issue on GitHub.

We welcome contributions from the community in form of bug fixes, feature enhancements, documentation updates, etc. All contributions are processed through pull-requests on GitHub. Please follow our contributing guidelines when submitting pull-requests.

To pass the formatting check, use this with a new version of clang-format: find nalu.C unit_tests.C ./include ./src ./unit_tests \( -name "*.cpp" -o -name "*.H" -o -name "*.h" -o -name "*.C" \) -exec clang-format -i {} +
