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.

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.

2. create a mesh,
3. apply boundary constraints and loads,
4. analyse,
5. and finally post-process (visualize) the results.
