FEM CalculiX Cantilever 3D

Introduction
! DO NOT TRANSLATE AT THE MOMENT ! This example is meant to check if FEM module is set up properly to run an simple mechanical static Finite Element analysis. It shows how to run an analysis and how to visualize the results.



Requirements

 * FCVersion=0.16.6377 or above.
 * This could be checked at the menu Help --> about FreeCAD --> Revisionnumber which has to be bigger than 6377
 * No external software is needed for loading the example file, viewing the mesh and geometry as well as for visualizing the results.

Load File

 * 1) Start FreeCAD
 * 2) The Start Workbench should be loaded




 * 1) Go to the example projects and click on "Load an FEM analysis example"
 * 2) If due to further operations some geometry, constraints or the results are broken or deleted just repeat the steps above.

Create an analysis and mesh the geometrical model

 * 1)  Switch to the FEM Workbench

Material

 * 1) Next step will be to give an material to our model

Constraints

 * 1) What needed next is to add some fixed and force constraints to our model.

FEM Mesh

 * 1) The two possibilities by either the build in mesher Netgen and the external mesher GMSH will be shown in this tutorial. There are various

Netgen

 * 1)  Select the shape you wish to mesh, in this case our Cube and click on [[Image:Fem_FemMesh.svg|32px]] Create FEM mesh.

GMSH

 * 1) If FreeCADs build in mesher Netgen is not available the usage of Macro_GMSH is recommended, and is used for this example.

Running the Solver

 * 1) Select the solver object  [[Image:Fem_Solver.svg|32px]] of the analysis in tree view and press  [[Image:Fem_QuickAnalysis.svg|32px]] Quick Analysis from the icon tool bar
 * 2) The analysis will be made and the result object should be created.

Analyzing Results

 * 1) Select [[Image:Fem_Result.svg|32px]] Show result
 * 2) Choose among the different Result types to view the results
 * 3) The slider at the bottom can be used to alter the mesh to view the deformation in a simplified manner
 * 4) To remove the results select [[Image:Fem_PurgeResults.png|32px]] Purge results

We are now finished with the basic workflow for the FEM Module.
