Modules

Multiple

There are several pull requests that affected multiple modules. Important features include the initial development of aeromaps (for controls development), initial development of the reduced order modules of AeroDisk and Simplified-ElastoDyn (overviews of each below).

#1295 Reduced order models: AeroDisk and Simplified-ElastoDyn (SED) (@andrew-platt)

#2332 Minor bugfix: ED blade file parsing (no PichAxis column), AD warnings (@andrew-platt)

#2415 Lidar bug fix + other minor changes (@bjonkman)

#2416 SED+ADsk: update registry comments slightly (@andrew-platt)

AeroDyn 14 (deprecated, option replaced by AeroDisk)

AeroDyn14 has been removed from the code base as it has been superseded by AeroDyn15 (now called simply AeroDyn) for many years.

#2267 AeroDyn14 removal (@andrew-platt)

AeroDisk

AeroDisk is a new module for a disk actuator aerodynamic module for modeling turbine aerodynamics as a simple actuator disk. This module assumes that the rotor is a rigid disk, and so, should be not be combined with BeamDyn or ElastoDyn with blade degrees of freedom enabled; it is meant to be used with the new Simplified-ElastoDyn module. This is useful for modeling turbines that are not of interest in very large wind farms modeled by FAST.Farm, but whose wake dynamics are needed for turbines further into the wind farm that are of interest. We do not recommend using this module with standalone OpenFAST simulations.

  • New input file

#2575 ADsk: correction to disk average velocity equations (@andrew-platt)

AeroDyn

AeroDyn improvements include a new input file, new options in BEM to improve aerodynamics for skewed and sheared inflow and coned rotors, nacelle drag, visualization improvements, unsteady aero for tailfins, an improved unsteady airfoil aerodynamics driver, multi-rotor support in the interface library, a simple ground effect model for OLAF wakes, using InflowWind pointers for data access, and many bug fixes. With the removal of AeroDyn14, AeroDyn15 is now simply referred to as AeroDyn in the input files and code (documentation may not be fully updated).

  • Major input file changes
  • Driver input file changes

#2247 ED: Add inputs for the off-diagonal terms of the platform moment of inertia matrix (@luwang00)

#2561 ED: Extended yaw-friction modeling (@luwang00)

ExtInflow (formerly OpenFOAM)

ExtInflow (also called ExternalInflow) is the renamed OpenFOAM module. The name change better reflects what this module does as it can couple to more than just the OpenFOAM solver used in SOWFA.

#1687 ExternalInflow: rename files, change names in files (@andrew-platt)

#2443 Fixes in ExtInflw (heap-buffer-overflow, index flip, empty structure) (@marchdf)

ExtLoads

ExtLoads is a new module for blade resolved fluid-structure interaction with CFD codes such as AMR-Wind. This module is accessed through the CPP interface to OpenFAST.

#1932, #1946 Blade resolved loads from CFD (@gantech, @deslaughter, @psakievich, @jrood-nrel, @andrew-platt)

#2001 ExtLoads: move integers from inputs to parameters (@andrew-platt)

#2009 ExtLoads module: Use pointers for wind (@andrew-platt)

#2226 Fix turbine indexing on ExtLoads Restart (@ndevelder)

#2412 ExtLd: require use of InflowWind (@andrew-platt)

HydroDyn

The HydroDyn module was completely restructured with wave dynamics split out into a new module, SeaState (documented below). HydroDyn now accesses wave-field data through a pointer to the data held in the SeaState module. Other improvements include large yaw angle dynamics, wave loads at the displaced position in surge/sway, MacCamy-Fuchs diffraction for strip-theory members, wave stretching (various models) with load smoothing, constrained New Wave theory, new strip-theory hydrostatic solution valid for near-horizontal members at the free surface, and bug fixes.

#2444 HD: Reimplement the initialization of low-pass-filtered potential-flow body positions for ExctnDisp=2 (@luwang00)

InflowWind

The InflowWind module data handling was updated so that AeroDyn, ExtInflow, and Lidar can retrieve FlowField data through a pointer. The driver was updated to allow the export of VTK slices in XY planes at a chosen elevation from any wind format. This can be useful when visualizing wind flow in an OpenFAST or FAST.Farm simulation.

  • Driver input file changes
  • library API changes

#2405 [BugFix] remove extra summary file write from MAP++ (@sanguinariojoe, @andrew-platt)

#2420 MAP: change strncpy to use macro MAP_STRNCPY (@andrew-platt)

MoorDyn

MoorDyn received several new features including coupled pinned bodies, ramping of inertial loads to better handle startup transients, updated body kinematics, linear damping for rod elements, mean load dependent dynamic stiffness for viscoelastic mooring lines, and mooring line failures. Visualization of shared mooring lines for FAST.Farm is also included.

There are a few minor bug fixes for the library.

#2191 [BugFix] blank line not handled by InitFileInfo (@andrew-platt)

#2223 SetErrStat referenced incorrectly in VTK.f90 (@andrew-platt)

Registry

The Registry was completely rewritten in C++ (included in #1609, @deslaughter) significantly cleaning up the code. New features include pointer handling and new data structures to streamline packing and unpacking for saves/restarts.

#1618 [BugFix] OpenFAST Registry on Windows (@deslaughter)

#1625 Add support for pointers in OpenFAST Registry generated Pack and Unpack subroutines (@deslaughter)

#2365 Bugfix for OpenFAST Registry incorrectly restoring pointers in modules with CObjs (ExtLd) (@deslaughter, @gantech)

#2519 Use B4Ki to store array bounds during pack/restore of TurbineType to file (@deslaughter)

SeaState

The SeaState module contains all the wave dynamics previously included within HydroDyn. As a standalone module, data is stored in the WaveField data structure which is accessible from other modules through pointers. The first implementation of this code was developed by @HaymanConsulting (#970).

  • New input file

#2113 SeaState: replace pointer attribute with allocatable (@bjonkman)

Simplified-ElastoDyn

The Simplified-ElastoDyn module (SED) is a one degree of freedom rigid structural model useful for cases where a full structural model is not needed (for example, leading turbines in a FAST.Farm simulation). This speeds up computations significantly, but at the expense of accuracy. So it is only recommended that this be used within FAST.Farm for turbines where load calculations are not needed. This is often paired with the AeroDisk module.

  • New input file

#2406 Correct issues with SED (logic lost in prior merge) (@andrew-platt)

SubDyn

SubDyn improvements include a new 6x6 spring element, removal of some stiffness terms for cable pretension, a few bug fixes, and code cleanup.

Testing and input file processing

There were several updates and improvements to the testing system and GitHub actions.

openfast_io

This Python based library provides OpenFAST users with library to read and write OpenFAST input files. This library will be able usable for updating input files starting with this release of OpenFAST going forward. This is designed for inclusion in other workflows, such as WEIS.

Input file changes

This release brings a large number of input file changes and rearrangements with multiple new modules. A partial list of changes can be found here: https://openfast.readthedocs.io/en/main/source/user/api_change.html. However, we recommend that if you start by comparing to the complete set of input files found in the regression tests: https://github.com/OpenFAST/r-test/tree/v4.0.0 (example input files from the regression testing)

Precompiled Windows Binaries

The binary files in this release were built with the Visual Studio solution files distributed with OpenFAST (not using cmake), using

  • Intel Fortran compiler 2021 (Update 2, w_oneAPI_2021.2.0.243) with Microsoft Visual Studio Community 2019
  • Microsoft Visual C++ 2019 (C), for build in Matlab
  • MATLAB Version: 9.9.0.1857802 (R2020b) Update 7
  • Executables with _OpenMP or _OMP in the name are built with OpenMP libraries and linked with dynamic libraries.

The other OpenFAST executables DO NOT require these redistributable libraries to be installed. Instead, they were built with static libraries.

openfast - v3.5.0

Overview of v3.5.0

This release includes several new features, bugfixes, and improvements.

New Features

New features include Lidar simulation within the InflowWind module, the ability to simulate a marine hydro-kinetic turbine (MHK) on a floating platform with an downward pointing tower, VTK based visualization with the BeamDyn driver, and a non-uniform point distribution in the OpenFOAM module for improved coupling fidelity to CFD with actuator lines.

Bugfixes

There were several bugfixes in SubDyn, AeroDyn, and HydroDyn. See below for details.

Improvements

AeroDyn received a minor update to the BEM solver to better model cone and prebend.

The QuKi (quad kind, 128 bit reals) was removed from OpenFAST allowing for building with on architectures that don't support 128 bit reals, and compilers that could not use it.

The build system was completely overhauled to improve general usability. This includes support for the Flang compiler in addition to the GCC and Intel compilers, the ability to install LAPACK and BLAS from source with CMake (USE_LOCAL_STATIC_LAPACK option), improved support for Ninja on all platforms, the option to directly build FAST_SFunc from CMake for linking OpenFAST with Simulink, and some minor cleanup for better readability.

Input file changes

The InflowWind input file has a new section for the Lidar simulator. There are also some minor changes to the C++ interface. See the end of the Changelog below for a summary, or see https://openfast.readthedocs.io/en/main/source/user/api_change.html. For sample input files, take a look at the regression tests at https://github.com/OpenFAST/r-test/tree/v3.5.0 in the r-test submodule for OpenFAST.

NOTES

Unlike previous releases of OpenFAST, there is now NO NEED for a MAP++ DLL; this code has been statically linked into the executables.
FAST.Farm_x64_OMP.exe is built with OpenMP libraries and linked with dynamic libraries.
You will need this Intel Fortran redistributable package installed to run FAST.Farm_x64_OMP.exe if you do not already have Intel Fortran 2019 Update 5 installed. See the installation instructions here: https://software.intel.com/content/www/us/en/develop/articles/redistributable-libraries-for-intel-c-and-fortran-2019-compilers-for-windows.html.
You may also need a redistributable library for Visual Studio installed. See instructions here: https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0
The other OpenFAST executables DO NOT require these redistributable libraries to be installed. Instead, they were built with static libraries.

openfast - OpenFAST v2.2.0

General

  • Simulink interface updated and improved
  • OpenFAST Registry made optional and all module-types files added to version control (https://github.com/OpenFAST/openfast/pull/337)
  • Consolidated modules-ext and modules-local into modules and added module README's
  • Solve Option 2 Performance enhancements
    • Parts of the SolveOption2 algorithm have been moved to the the AdvanceStates routine so that BeamDyn, InflowWInd, AeroDyn, and ServoDyn use calculated inputs instead of extrapolations for inputs at t+dt. This change allows BeamDyn to use calculate rotations and AeroDyn/DBEMT to use calculated velocities, which otherwise would require a correction step. In DBEMT this was a problem with high turbulence and low wind speeds.

  • Add safety on number of lines and number of fields per line when WaveMode=6 (Should Fix #118)
  • Always initialize WaveElevSeries if WaveElevXY is set
  • Update array bounds in calculation in Morrison
