This repository contains FAST.Farm inputs files for NREL's 10-turbine shared-mooring array design using the DTU 10 MW spar. The FAST.Farm input files are organized in these directories:

• CommonFiles: shared input files for ElastoDyn, HydroDyn, MoorDyn, and AeroDyn.
• TurbulentWind: inputs for a FAST.Farm run using TurbSim inflow wind (includes turbsim input files)
• SteadyWind: inputs for a FAST.Farm run using steady inflow wind

Changes from the input files used in the paper include the following:

• TurbSim Low resolution and high resolution grid sizing, and grid sizing in the farm.fstf file were changed based on guidance from https://github.com/OpenFAST/python-toolbox/tree/main/pyFAST/fastfarm.
  • Low resolution grid spacing changed from 60 m to 25 m
  • Low resolution grid width changed from 10980 m to 7150 m
  • Low resolution grid height changed from 600 m to 575 m
  • High resolution grid spacing changed from 15 m to 5 m
  • TurbSim time step changed from 0.5 s to 0.1 s
• Simulation length for the TurbulentWind case changed from 4600 seconds to 600 seconds.
• Open.FAST API changes from OpenFAST v3.0.0 to v3.4.1. See https://openfast.readthedocs.io/en/main/source/user/api_change.html for more information.
