data reduction tools for general aerodynamic measurements

Project description

Latest PyPI version

python libraries for use in the reduction and analysis of experimental or computational aerodynamic data



add the following to any function or scope in a program and the execution time will be logged (must use logging library and add the “aiolos_code_instrumentation.timer” logger)

>>> from code_instrumentation.timer import timer
>>> _ = timer.Timer()

to display the execution time, add the timer logger and set the logging lever to TIMER

>>> import logging
>>> from aiolos_code_instrumentation.add_logging_level import TIMER
>>> log = logging.getLogger("aiolos_code_instrumentation.timer")
>>> log.setLevel(TIMER)

to output to terminal:

>>> streamhandler = logging.StreamHandler()
>>> streamhandler.setLevel(TIMER)
>>> log.addHandler(streamhandler)

this can all be achieved using a log.conf file as well.


the unit conversions are to be used when importing data to convert the data to base SI units. e.g.:

>>> import commissoning_tools.units as units
>>> p = read(data_file_pressures_psi) * units.psi # Yeilds a pressure value in Pascals
>>> t = read(data_file_temperatre_C) + units.celsius # Yeilds a temperature value in Kelvin
base units are:
  • length –> meter, m
  • time –> second, s
  • mass –> kilogram, kg
  • temperature –> Kelvin

derived units use only the base. i.e. velocity is m/s, pressure is Pa (N/m^2)

Package Maintenance

  1. To contribute to the development of the Package, first clone the repository locally and create a development branch:

    $ git clone

    $ git branch <branch name>

    $ git branch dev-cfd-tools (e.g.)

  2. Create a local environment (using venv or virtualenv) and activate

    $ python3 -m venv <virtual environment name>

    $ python3 -m venv venv (e.g. will create venv\ directory)

    $ venv\Scripts\activate.bat (windows)

    $ source venv/bin/activate (linux)

  3. install requirements

    $ python3 -m pip install –upgrade pip

    $ python3 -m pip install -r requirements.txt

  4. When testing the functionality, ensure that the local version of the package is installed in the virtual environment

    $ python3 -m pip install -e <path to local copy of aiolos-tools>

    $ python3 -m pip install -e C:\users\christopher\aiolos-tools (e.g.)

Merging branches

Uploading changes

  1. Freeze development dependencies (remove an references to the aiolos-tools package if they exist)

    $ python3 -m pip uninstall aiolos-tools

    $ python3 -m pip freeze > requirements.txt

  2. commit changes to git:

    $ git add .

    $ git commit -m “commit message”

  3. Increment version:

    $ bumpversion <major | minor | patch>

    $ bumpversion minor (e.g.)

  4. Push to github:

    $ git push <remote_name> <branch_name>

    $ git push origin master (e.g.)

  5. Creating distribution archives (should only be done with master branch)

    $ python3 -m pip install –upgrade setuptools wheel

    $ python3 sdist bdist_wheel

  6. Uploading to PyPI (should only be done with master branch)

    $ python3 -m twine upload dist/*


  1. for use

    $ python3 -m pip install aiolos-tools

  2. for development

    $ git clone $ python3 -m pip install -e <path to local copy of aiolos tools> $ python3 -m pip install -e c:\users\christopher\aiolos-tools


  1. “numpy”
  2. “matplotlib”
  3. “scipy”
  4. “pandas”


current version : 0.2.4


0.0.0 : initial release based on aiolos-commissioning-tools 0.2.8

0.2.4 : added boundary layer and aspg procedural functions and some plotting features but removed @np.vectorize decorators in some places
