OpenFAST is a wind turbine simulation tool which builds on FAST v8. FAST.Farm
extends the capability of OpenFAST to simulate multi-turbine wind farms. They were
created with the goal of being community models developed and used by research
laboratories, academia, and industry. They are managed by a dedicated team at the
National Laboratory of the Rockies. Our objective is to ensure that OpenFAST and FAST.Farm
are sustainable software that are well tested and well documented. If you'd like
to contribute, see the `Developer Documentation `_
and any open GitHub issues with the
`Help Wanted `_
tag.
**OpenFAST is under active development**.
Part of the WETO Stack
----------------------
OpenFAST 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:

FAST v8 - OpenFAST
------------------
The transition from FAST v8 to OpenFAST represents the effort to better
support an open-source developer community around FAST-based aero-hydro-servo-
elastic engineering models of wind-turbines and wind-plants. OpenFAST is the
next generation of FAST analysis tools. More information is available in the
`transition notes `_.
FAST v8, now OpenFAST, is a physics-based engineering tool for simulating the coupled dynamic
response of wind turbines. OpenFAST joins aerodynamics models, hydrodynamics models
for offshore structures, control and electrical system (servo) dynamics models,
and structural (elastic) dynamics models to enable coupled nonlinear aero-
hydro-servo-elastic simulation in the time domain. The OpenFAST tool enables the
analysis of a range of wind turbine configurations, including two- or
three-blade horizontal-axis rotor, pitch or stall regulation, rigid or
teetering hub, upwind or downwind rotor, and lattice or tubular tower. The wind
turbine can be modeled on land or offshore on fixed-bottom or floating
substructures. OpenFAST is based on advanced engineering models derived from
fundamental laws, but with appropriate simplifications and assumptions, and
supplemented where applicable with computational solutions and test data.
With OpenFAST, you can run large numbers of nonlinear time-domain simulations
in approximately real time to enable standards-based loads analysis for predicting
wind system ultimate and fatigue loads. You can also linearize the underlying
nonlinear
