EasyFEA is a user-friendly Python library that simplifies finite element analysis. It is flexible and supports different types of simulations without requiring users to handle complex PDE formulations. You will find below the finite element analysis that you can conduct using EasyFEA:
- Linear Elastostatic and Elastodynamics simulations
- Nonlinear Hyperelastic Static simulations
- Euler-Bernoulli beam simulations
- Thermal simulations
- Phase-field damage simulations for quasi-static brittle fracture
- Weak forms simulations
- Digital Image Correlation (DIC) and Parameter identification
- Stochastic phase-field simulations
For each simulation, users create a mesh and a model. Once the simulation has been set up, defining the boundary conditions, solving the problem and visualizing the results are straightforward.
Numerous examples of mesh creation are available in the Meshes gallery.
The simplest and quickest introduction is shown below and is available in the Beginner’s Guide.

Refer to the documentation for detailed installation and usage details.
EasyFEA can be easily installed from PyPI using pip, compatible with Python versions 3.9 through 3.13:
pip install EasyFEA
You can also install EasyFEA with the source code using the pip install . command in the downloaded or cloned EasyFEA folder.
EasyFEA uses several libraries, such as NumPy and Gmsh - as such, the following projects are required dependencies of EasyFEA:
numpy- Fundamental package for scientific computing with Python.gmsh(>= 4.12) - Three-dimensional finite element mesh generator.scipy- Fundamental package for scientific computing in Python.matplotlib- Plotting package.pyvista- Plotting package.numba- Compiling Python code using LLVM.pandas(3.9 <= Python <= 3.12) - Powerful data structures for data analysis.imageioandimageio[ffmpeg]- Library for reading and writing a wide range of image, video, scientific, and volumetric data formats.meshio- I/O for many mesh formats.
EasyFEA includes a few optional dependencies for reducing resolution time or for performing DIC:
pypardiso(Python > 3.8 & Intel oneAPI) - Library for solving large systems of sparse linear equations.petscandpetsc4py- Python bindings for PETSc.opencv-python- Computer Vision package.
EasyFEA uses Object-Oriented Programming (OOP) with the following naming conventions:
PascalCasingfor classescamelCasingfor propertiesSnake_CasingorSnake_casingfor functions/methods
In this library, objects can contain both public and private properties or functions.
Private parameters or functions are designated by a double underscore, such as __privateParam. In addition, parameters or functions beginning with an underscore, such as _My_Function are accessible to advanced users, but should be used with caution.
