Input output file readers

This package contains readers and writers for typical files used in OpenFAST simulations:

  • FAST input file (.fst, .dat, .txt), Class: FASTInputFile, file: fast_input_file.py.
  • FAST output file (.out, .outb, .elev), Class: FASTOutputFile, file: fast_output_file.py.
  • FAST linearization file (.lin), Class: FASTLinearizationFile, file: fast_linearization_file.py.
  • FAST summary file (.sum.yaml), Class: FASTSummaryFile, file: fast_summary_file.py.
  • TurbSim binary file (.bts), Class: TurbSimFile, file: turbsim_file.py.
  • CSV file (.csv, .dat, .txt), Class: CSVFile, file: csv_file.py.

Main architecture and interface

A separate python file and class is used for each file format. The classes inherit from the standard File class, present in the file file.py.

The object returned by each class is (or behaves as) a dictionary. The main methods are:

  • object = class() : create an instance of a file object
  • object = class(filename): create an instance of a file object, and read a given file
  • object.read(filename): read the given file
  • object.write(filename): write the object to a file (may overwrite)
  • object.toDataFrame(): attempts to convert object to a pandas DataFrame

Additional methods may be present depending on the file format.

Examples

Examples scripts are found in this folder. Below are simple examples to get started:

Read an AeroDyn file, modifies some values and write the modified file:

from pyFAST.input_output import FASTInputFile
filename = 'AeroDyn.dat'
f = FASTInputFile(filename)
f['TwrAero'] = True
f['AirDens'] = 1.225
f.write('AeroDyn_Changed.dat')

Read an OpenFAST binary output file and convert it to a pandas DataFrame

from pyFAST.input_output import FASTOutputFile
df = FASTOutputFile('5MW.outb').toDataFrame()
time  = df['Time_[s]']
Omega = df['RotSpeed_[rpm]']

Read a TurbSim binary file

from pyFAST.input_output import TurbSimFile
ts = TurbSimFile('Turb.bts')
print(ts.keys())
print(ts['u'].shape)
