This repository serves as a container for regression test data for system level and module level testing of OpenFAST. The repository contains:
- input files for test case execution
- baseline solutions for various machine and compiler combinations
- turbine specific inputs
The baseline solutions serve as "gold standards" for the regression test suite and are updated periodically as OpenFAST and its modules are improved.
This directory contains module level tests for the modules found in the source code at openfast/modules-local.
These BeamDyn specific cases are configured to run with the BeamDyn driver program rather than with a glue code.
This directory contains system level tests for the various "glue codes" or drivers found in the source at openfast/glue-codes.
These are the system level test cases taken from the FAST V8 CertTests.
Each test case directory contains the OpenFAST input file, .fst, and all other case specific inputs. All turbine specific inputs are linked by relative paths to their corresponding turbine data directory. See the individual test case README's for more information regarding the particular turbine model and portion of the OpenFAST system that is being tested.
The included turbine directories are:
- 5MW_Baseline - NREL offshore 5-MW baseline wind turbine
- AOC - Atlantic Orient Company 15/50 wind turbine
- AWT27 - Advanced Wind Turbine program blade 27
- SWRT - Small Wind Research Turbine
- UAE_VI - Unsteady Aerodynamics Experiment research wind turbine
- WP_Baseline - WindPACT 1.5-MW baseline wind turbine
The CertTest cases were recently renamed from the old style TestNN to more descriptive names. In general, the turbine abbreviation begins the case name followed by a concise description of the physics involved.

The regression test compares locally generated solutions to the baseline solutions generated on a series of machine and compiler combinations. Currently, the supported machine/compiler combinations for successful regression testing are:
- linux-intel
- macos-gnu
- windows-intel
These results were generated on a MacBook Pro running on macOS Sierra 10.12.4. The OpenFAST binary was compiled with gfortran installed through Homebrew's gcc package at gcc version 6.3.0 (Homebrew GCC 6.3.0_1).
These results were generated on NREL's Peregrine HPC cluster running on Red Hat Enterprise Linux Server release 6.3 (Santiago). The OpenFAST binary was compiled with Intel's ifort compiler version 16.0.2.
These results were generated on a Dell Latitude E7440 running Windows 7 Enterprise SP 1. The OpenFAST binary was compiled with Intel's Visual Fortran 17 update 4.
The baseline directories can be updated with the included updateBaselineSolutions.py. This script copies locally generated OpenFAST solutions into the appropriate machine - compiler baseline solution directory.
Usage: python updateBaselineSolutions.py source_directory target_directory system_name compiler_id
Example: python updateBaselineSolutions.py local/solution/TestName target/solution/TestName [Darwin,Linux,Windows] [Intel,GNU]
The cases using the 5MW turbine require an external controller for ServoDyn. The source code for three external controllers are provided, but they must be compiled and installed. For Linux and Mac systems, a python script is included at glue-codes/fast/compileDISCON.py which executes cmake and compiles with make automatically. The compile script is called with no arguments:
python compileDISCON.py
On Windows systems, cmake can generate a Visual Studio project to compile and install the controllers. Create a build directory at
r-test/glue-codes/fast/5MW_Baseline/ServoDyn/DISCON/buildr-test/glue-codes/fast/5MW_Baseline/ServoDyn/DISCON_ITI/buildr-test/glue-codes/fast/5MW_Baseline/ServoDyn/DISCON_OC3/build
and run cmake in each one replacing your Visual Studio version and architecture in the following command:
cmake -G "Visual Studio 14 2015 Win64" ..
Ultimately, three .dll's should be compiled and placed in the 5MW_Baseline parallel to the test cases that will be executed. For example, if the regression test is executed automatically with ctest or manualRegressionTest.py, all case files will be copied to openfast/build. In this case, these three controller libraries must exist:
