AeroDyn is an aerodynamics software library (module) for use by designers of horizontal-axis wind turbines. It is written to be interfaced with a number of dynamics analysis software packages (such as FAST, ADAMS, SIMPACK, and FEDEM) for aero-elastic analysis of wind turbine models. AeroDyn and its downloadable user's guide assume the user is an experienced wind turbine aerodynamics and dynamics analyst.

The aerodynamics model in AeroDyn is a detailed analysis that includes blade-element/momentum theory (with modifications to improve accuracy in yawed flow), dynamic stall, and an optional dynamic inflow theory. GL Wind issued a certificate of evaluation for AeroDyn as used by FAST and ADAMS in 2005.

The AirfoilPrep preprocessor is available to create the input files for the aerodynamics tables in AeroDyn. TurbSim is also available to create full-field turbulence for use in AeroDyn v13's InflowWind module.

The most recent version of AeroDyn available for use with FAST 8 may be downloaded from the AeroDyn v14 page.

You may download the following files (compatible with FAST v7) from our server:


  • AeroDyn Change Log (v13.00.02a-bjj, 38 KB, 22-February-2013)

    This is a list of changes made to the code. Look at this text file to see if we've made worthwhile changes since you received your previous version of AeroDyn. It is also included in the archive.

  • AeroDyn User's Guide (v12.5, 441 KB, 24-December-2002)

    This is the AeroDyn User's Guide. It explains what AeroDyn does and how you can use it. It is also included in the archive. Note: Some of the recent changes to AeroDyn are not included in this guide; please also read the Addendum to the AeroDyn User's Guide .

  • Addendum to the AeroDyn User's Guide (v13.00.02a-bjj, 23-February-2013)

    Because we have not had the time to update the AeroDyn User's Guide, we have temporarily left AeroDyn v13.00.02a-bjj as an "alpha" version. We have created a document to guide you through the major changes in the updated code and to document the updated AeroDyn interface. We encourage you to read it.

  • AeroDyn Theory Manual (Future version TBD, 1.2 MB, 6-December-2005)

    This is the AeroDyn Theory Manual. It describes the algorithms used in the code. Please note: The algorithms described in the manual are what we intend to have in the routines for a future release.

AeroDyn Archives (v13.00.02a-bjj, 23-February-2013)

Both AeroDyn archives contain the AeroDyn source code, change log, user's guide, and sample input files. If you want to compile the source code, you will also need to download and compile source code from NWTC Subroutine Library v1.07.00b-mlb and InflowWind v1.01.00b-bjj.
