Get data from Sesam Interface Files

Project description


Work easily with data from SESAM Interface Files.



Python package that enables easy extraction of data from SESAM Interface Files.

The following file formats are currently supported:

  • Formatted finite element model file (.FEM)
  • Formatted interface file (.SIF)
  • Unformatted interface file (.SIU)

Getting started

Install the latest release

pip install freesif

... and import it into a script

from freesif import open_sif



These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.


Install Python version 3.6 or later from either or

Clone the source code repository

At the desired location, run:

git clone


To get the development environment running:

... create an isolated Python environment and activate it,

python -m venv /path/to/new/virtual/environment


... install the dev dependencies in requirements.txt,

pip install -r requirements.txt

.. and install the package in development mode.

python develop

You should now be able to import the package in the Python console,

import freesif

Running the tests

The unit tests are automated using the unittest and pytest framework. Run the test by...

pytest --cov=freesif --cov-report term-missing tests/

Building the package

Build tarball and wheel distributions by:

pip install wheel
python sdist bdist_wheel

The distribution file names adhere to the PEP 0427 convention {distribution}-{version}(-{build tag})?-{python tag}-{abi tag}-{platform tag}.whl.


Packaging, unit testing and deployment to PyPi is automated using GitHub Actions.


We apply the "major.minor.micro" versioning scheme defined in PEP 440.

Cut a new version by applying a Git tag like 1.0.1 at the desired commit and then setuptools_scm takes care of the rest. For the versions available, see the tags on this repository.
