Range Software - FEA

Range FEA is an open-source desktop application for computer-aided engineering using the Finite Element Method. It provides an integrated environment for mesh generation, simulation setup, and 3D visualisation of results across a range of physics domains — including structural stress, heat transfer, fluid dynamics, acoustics, electrostatics, and magnetostatics.

The application is built on Qt6 and ships with a standalone CLI solver (fea-solver) alongside the main GUI (fea). Mesh generation uses the embedded TetGen library for automatic tetrahedral meshing.
