Description

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, 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.
