2.1.1 - (2020-06-15)

Mostly some minor bug fixes and a function for generating rotor performance files using AeroDyn.

Major Updates

  • generate_rotperf_FAST is included in the functionalities in turbine.py now. This makes it possible to call OpenFAST and use aerodyn or beamdyn (pending) to generate the - Cp, Ct, Cq tables. Slow, but useful for verification.
  • Include GBEff and GenEff appropriately in turbine.rated_torque and controller.VS_Rgn2K calculations

Minor Updates

  • min_pitch was not appropriately accounted for if user-defined
  • print size of arrays in Cp_Ct_Cq.txt files
  • minor typos and commenting cleanup

2.1.0 - (2020-04-21)

Mostly major updates to the post processing scripts. Some of these may be considered API changes, but we'll treat them as feature adds for now.

A brief overview of major changes:

  • load_output is renamed to load_fast_out
  • load_fast_out now writes out a list of dictionaries containing openfast data, where each list item corresponds to an OpenFAST output case.
  • All plotting functions were moved to a class FAST_plots
  • plot_fast_out only receives the output from load_fast_out for the OpenFAST data to plot
  • plot_spectral is included for a number of frequency-domain based plotting capabilities
  • trim_fast_out is modified to only modify data passed in the new dictionary-based structure
  • some verbosity flags have been included

2.0.0 - (2020-03-04)

Admittedly poor versioning since the last release. Lots of updates...

API Changes

  • Re-org of some functionalities
    • turbine.load_from_text is now turbine.utilities
    • utilities.write_param_file is now utilities.write_DISCON
  • Include flap controller tuning methods and related inputs to DISCON.IN
  • Remove unnecessary control inputs in DISCON.IN (z_pitch_*)

Other changes

  • Updates to floating filtering methods
  • Updates to floating controller tuning methods to be more mathematically sound
  • Generic flap tuning - employ reading of AeroDyn15 files with multiple distributed aerodynamic control inputs
  • Test case updates and bug fixes
  • Example updates to showcase all functionalities
  • Updates to OpenFAST output processing and plotting scripts
  • All related improvements and updates ROSCO controller itself

1.0.1 - (2020-01-29)

  • Major bug fixes in second order low-pass filters
  • Minor bug fixes for pitch saturation and filter mode settings
  • Minor updates in tuning scripts

1.0.0 - (2020-01-22)

  • Version 1.0 release - initial transition from DRC-Fortran with major updates and API changes
