FEM Solver

Preface

This page collects all informations about the FEM solver system used by FreeCAD's FEM Module. The interface between a solver and FreeCAD in pre- as well as post processing is done by text files. This means in theory any solver which uses text files is able to work together with FreeCAD FEM.

Solver version in various Linux distributions
