Finite Element Analysis GitHub Repositories (2026) · Open Source Tools

3D visualization and mesh analysis for science and engineering

2D structural analysis in Python

One open-source modeler for structures, heat and fluids, built from scratch in pure Rust: parametric part in, verified results out. Automatic all-hex and tet meshing, our own nonlinear implicit and explicit FEA, heat transfer and lattice Boltzmann CFD — every result checked against theory. For engineers and AI agents alike. Free, forever.

Open finite element infrastructure for nonlinear computational mechanics.
