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:

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.
