### Find tutorials and examples on LiveCD or installed CAELinux distro

You can find all of these tutorials on the LiveCD or your local installed copy of CAELinux. Log in using the caelinux username account and you will have access to all of this in one spot. At the CAELinux KDE desktop you will find the "CAELinux Docs" lightning bolt icon with a yellow background. Double-click the icon and choose the "Tutorials" directory. Here you will find a directory with all of the necessary files and flash videos. The path to this location is /opt/helpers/docs/tutorials/. They are also available here via the web but will generally load slower than a local source.

### CAELinux 2011 tutorials

You can find the new video tutorials for CAELinux 2011 on that page of the Wiki Doc:CAELinux2011_Tutorials

### Salome & OpenFOAM tutorial: 3D CFD analysis of a Y-shaped pipe (CAELinux 2008 / CAELinux 2007)

This tutorial shows how to use Salome & OpenFOAM to:

- create the 3D CAD geometry of a Y-shaped pipe in Salome
- generate a free tetrahedral mesh for the CFD analysis in Salome
- create an OpenFOAM simulation case and import the mesh from UNV file
- model the transient incompressible fluid flow in the pipe
- visualize the results in ParaView

This tutorial is subdivided in three parts: Geometry, Meshing & CFD analysis.

**Flash video tutorials:**

Part 1 notes for CEALinux 2008 users: This tutorial video was created with the CAELinux 2007 version software packages. This includes Salome-Meca version 3.2.6. While this tutorial is still applicable to CAELinux 2008 there is a known software bug in Salome-Meca 3.2.9. This will not allow you to use the "Extrude along a path" functionality with a wire type selection for the path of the swept circular face. There is a file packaged with the CAELinux2008 distro at this location /opt/helpers/docs/tutorials/pipe/Pipe1.hdf. The geometry is fully created in this file and can be used as a workaround if you don't figure out a different way to model the shape in the geometry mode of Salome.

Part 3 notes for CAELinux 2008 users: When creating the 13 isosurfaces for the pipe example in paraview it may not correctly set the default range. If you notice in the tutorial the range of the iso surfaces is between 0 and 0.13872. You may need to adjust this range setting in order to follow along with the tutorial.

### Guide to composite analysis

In this document you will find a guide to analize composite behavior.

### Another introductory tutorial: Salome-Meca 2008.1 GPL

This tutorial shows how to use Salome-Meca to analyse a **very** simple geometry subjected to tension (linear static analysis). The geometry is a rectangular filleted bar. The results are compared with stress values obtained from the literature for geometries with notches/fillets where stress concentrations will be present:

- Import 3D STEP geometry (created with
*VariCAD*for GNU/Linux), - create a mesh,
- apply boundary constraints and loads,
- analyse,
- and finally post-process (visualize) the results.

### Step-by-step guide for the modeling of a simple geometry and solving for its electric field with CAELinux

A guide for the absolute CAELinux beginners. You create a simple geometry with Salome, solve it with OpenFOAM and view it with Paraview. It also includes advanced post processing, which incorporates the calculation of the total energy of the electric field and its capacitance and the use of the sample utility to extract the field along a path.
