FAST v8.15.00 Available

Postby Bonnie.Jonkman » Thu Apr 14, 2016 1:17 pm

We have released a new version of the FAST v8 wind turbine multi-physics engineering software tool, along with its various modules, to our website.

FAST v8.15.00a-bjj is the latest public release under the FAST Modularization Framework. Major changes in v8.15 and its various modules from the previous release include the following:

  • We added visualization capability based on either surface or stick-figure geometry for model reference and initial configurations and time-series animation. FAST can now generate Visualization ToolKit (VTK) output files that can be read and viewed in standard open-source visualization packages such as ParaView or VisIt. See the example FAST-generated surface visualization graphic below.
  • In AeroDyn v15, we added unsteady airfoil aerodynamics, improved the existing blade-element/momentum code, and updated the documentation.
  • We added tower-based tuned mass dampers (TMDs) to ServoDyn, in addition to the nacelle-based TMDs previously available. Furthermore, the TMD capability (for both nacelle- and tower-based TMDs) has been updated with expanded functionality.
  • Documentation for BeamDyn has been updated.
  • Documentation for routines in the NWTC_Library has been added.
  • We fixed many bugs.
See the updated documentation and change logs for a complete list of enhancements and bug fixes.

FAST v8.15.00a-bjj is available at https://nwtc.nrel.gov/FAST8.

FAST v8.16.00 Available

We have released a new version of the FAST v8 wind turbine multi-physics engineering software tool, along with its various modules, to our website.

FAST v8.16.00a-bjj is the latest public release under the FAST Modularization Framework. Major changes in v8.16 and its various modules from the previous release include the following:
  • We added full-system linearization functionality for land-based wind turbines, including core (but not all) features of the InflowWind, AeroDyn v15, ServoDyn, and ElastoDyn modules and their coupling. While most physics in FAST are nonlinear, linearization of the underlying nonlinear system equations is often advantageous to understand the system response and exploit well-established methods and tools for analyzing linear systems.
  • In BeamDyn, we added the full finite-element mass and stiffness matrices of the blade model at time zero to the BeamDyn summary file; these are useful for checking the standalone blade natural frequencies.
  • We fixed a bug in BeamDyn related to how it is initialized when nonzero initial deflections/displacements are set in ElastoDyn.
See the updated documentation and change logs for a complete list of enhancements and bug fixes.

FAST v8.16.00a-bjj is available at https://nwtc.nrel.gov/FAST8.
