Finite Element Method for Solid Structures in Python.

SigmaEpsilon.Solid - High-Performance Computational Solid Mechanics in Python

Warning This package is under active development and in an alpha stage. Come back later, or star the repo to make sure you don’t miss the first stable release!

Highlights

Head over to the Quick Examples page in the docs to explore our gallery of examples showcasing what SigmaEpsilon can do! Want to test-drive SigmaEpsilon? All of the examples from the gallery are live on MyBinder for you to test drive without installing anything locally: Launch on Binder.

Overview

• A solid submodule to analyze and optimize solid structures of all kinds with the Finite Element Method. The implementations so far only cover linear behaviour, but with practically no limits on the complexity of the shape and topology of the domain under investigation.

Installation

sigmaepsilon.solid can be installed from PyPI using pip on Python >= 3.7:

>>> pip install sigmaepsilon.solid

or chechkout with the following command using GitHub CLI

gh repo clone sigma-epsilon/sigmaepsilon.solid

and install from source by typing

>>> pip install .

If you want to run the tests, you can install the package along with the necessary optional dependencies like this

>>> pip install ".[test]"

Documentation

Refer to the docs for further details on installation and usage.

Testing

To run all tests, open up a console in the root directory of the project and type the following

>>> python -m unittest

Dependencies

We use Numba's JIT compiler to speed up heavy computations, and it relies on the C++ redistributable package. It is likely already installed on your system, but if it is not, you can download it from Microsoft's website under "Other Tools, Frameworks, and Redistributables".
