SfePy — The Complete Guide: Free Finite Elements in Python for Research Problems
SfePy (Simple Finite Elements in Python) is an open-source package for solving finite element problems in Python. The problem is described in a Python file — mesh, regions, fields, boundary conditions and equations — and solved with the language’s usual scientific libraries.

- Elasticity — linear, and also large-deformation problems.
- Heat transfer — steady and transient.
- Acoustics — wave and resonance problems.
- Your own formulations — build equations from ready-made “terms”, or define new ones.
- 2D and 3D — with meshes from Gmsh and results in VTK format.
How it differs from FEniCS
Both tools are for people who write the equations themselves. In FEniCS you write the weak form in a mathematical language and get compiled code; SfePy is built entirely around Python and SciPy, easy to install (pip or conda) and very readable for anyone who knows that ecosystem. For very large problems and parallel computing, FEniCS is usually stronger.
