FEM Solver/it

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.
