Note: PyFEA is currently in the early stages of development and will evolve significantly over the course of the next few months. This project is currently on hold, but in its current state it is nearly usable (for finite difference at least) and if there is interest I may consider resuming development.

About

PyFEA is built to be an extendable suite for FE analysis in python, as this is a work in progress, no real documentation is currently provided but examples will be added to the examples folder as they are created. The focus will be on explicit FEM applied to transient simulations (and therefore will support steady-state, albeit at a maybe larger computational time).

Current progress

  • Simulations running! (see animation)
  • Interface with the gmsh api for meshing
  • Interface with tetgen for meshing (basic functionality only)
  • Generating meshes from STP and STL files

Meshing

simple_sim
