FEM Install

Introduction
To be able to do a Finite Element Analysis (FEA) using the FEM Worbench FreeCAD makes use of two external programms. One is used for generating the FEM-Mesh and the other for solving the system of equations.

FEM Mesh Generator
As meshing tool to create a FEM-Mesh netgen is used. See https://sourceforge.net/projects/netgen-mesher/ There are more possibilities to create an FEM-Mesh in FreeCAD. Check out the FEM-Mesh Wiki page(ToDo).

FEM Solver
For solving the system of equations CalculiX is used. See http://www.calculix.de/ Up To date (mid 2015) CalculiX is the only possibility to do a FEA in FreeCAD. Since there are more possibilities to get a valid FEM-Mesh it is recommended to install the Solver first.

Windwos
If either a stable or development version from Download is used no further software needs to be installed. Netgen and CalculiX are included in the FreeCAD download package.
