Will the bracket hold? Will the duct flow? Open-source FEA, CFD and meshing tools answer those questions on a laptop — the same solvers that sit under expensive commercial suites.
An Abaqus-syntax finite-element solver — the engine behind FreeCAD's structural and thermal analysis.
The industry-standard open-source CFD toolbox — fluid, thermal and multiphysics at any scale.
The go-to open mesh generator — scriptable, robust, and the front-end for many solvers.
FEA without leaving FreeCAD — a guided front-end over CalculiX and friends.
