FEM Solver
For solving the system of equations CalculiX is used. See http://www.calculix.de/ FreeCAD writes an CalculiX input file starts CalculiX and reads the output of CalculiX. It means CalculiX binary is standalone and independent from FreeCAD. Because of this and since there are more possibilities to get a valid FEM-Mesh it is recommended to install the Solver first. Up To date (mid 2015) CalculiX is the only supported Solver of the FEM module.
