FENIAX is an aeroelastic toolbox written and parallelized in Python, which acts as a post-processor of commercial software such as MSC Nastran. Arbitrary FE models built for linear aeroelastic analysis are enhanced with geometric nonlinear effects, flight dynamics and linearized state-space solutions about nonlinear equilibrium.
- Currently the code has been tested and is developed in Linux and MacOS.
- A minimum installation into the current environment is possible by navigating to the main directory and
pip install .
- However developer mode is recommended and also installing the full set of packages which include testing and visualisation capabilities:
pip install -e .[all]
- see setup.py file for the options available. Python 3.9+ is required but 3.11+ is recommended. Although it is not necessary, If conda is being used as package manager, one can make a specific environment as,
conda create -n feniax python=3.11
conda activate fem4inas
- If pytest has been installed, check everything is OK by running the tests:
pytest tests
- Thus a typical installation would comprise of these 4 steps:
conda create -n feniax.python=3.11
conda activate fem4inas
pip install -e .[all]
pytest tests

The most relevant examples in the code base are shown here, these and more can be found in the folder /examples
They are also part of a large test suite that is integrated into the development using CI/CD.
!!! tip Navigate to the code of the various examples, including the simulation input settings and postprocessing of the simulation --exactly as it was used for the articles backing the software.
