Welcome & Licence terms:

First of all, we would like to thank you for your interest in CAELinux which we hope will fullfill your needs in Computer Aided Engineering. This Linux distribution is based on the excellent PCLinuxOS system and includes an allways increasing number of open source modelling, simulation & design softwares. Most of the content (99%) of CAELinux is provided under the well known GPL  or  LGPL  (Gnu Public Licence) which allows you to freely use and redistribute these softwares but a small number of packages have their own licencing terms (GraphiteOne for example). If you intend to use this distribution for commercial work, it is your responsibility to verify the licencing terms of the softwares that you are using. The authors of the distribution are not responsible for these licencing aspects and this distribution and all the included softwares are provided without any warranty.


Introduction tutorial

For a very quick introduction to CAELinux capabilities, you should follow our Introduction Tutorial here:

Softwares included in CAELinux Beta 3

Here is a non exhaustive list of CAE software packages included in CAELinux as well as some key informations to get started. Some of the softwares can be started from Desktop shortcuts or from the CAE start menu, but most of the console based tools will require that you use our special shell called 'Command line tools' (in CAE start menu).

Software Use How to start Installation
directory
Documentation
Salome v3.2.1 3D CAD,

Meshing

Post Processing
Salome shortcut on desktop & in CAE start menu /opt/salome - HTML doc accessible inside the application
- Tutorials in /opt/helpers/docs
Code Aster STA8.3 multiphysics FE analysis Create a new FE analysis from templates with New FE Study shortcut on Desktop or directly use the interface called ASTK  /opt/aster - French documentation available from EFICAS.

- English doc (automatic translations) in /opt/helpers/docs/CodeAsterEnDoc, use SearchHelp.py from this directory to search for keywords in the English docs.

- Tutorials in /opt/helpers/docs

- Examples in /opt/aster/STA8.3/astest
Impact explicit FE  dynamics use shortcut in CAE start menu or start /opt/Impact.sh /opt/impact - Documentation available from the interface
- Examples in installation directory
OpenFOAM
v1.2
multipurpose CFD oriented solvers use 'Command line tools' from CAE start menu or start FoamX interface from CAE menu or /opt/FoamX.sh /opt/OpenFOAM - Examples & tutorials in /opt/OpenFOAM/OpenFOAM-1.2
Elmer v4.0 multiphysics FE package use the shortcut from CAE start menu or start 'ElmerFront' from CAE 'Command line tools' console /opt/elmer - Documentation in /opt/elmer

- Examples in /opt/elmer/ELMER4.0

- mesh converter from Salome: 

/opt/helpers/unv2ElmerUNV.py
Calculix pre-post & FE solver, Abaqus-like
syntax
from CAE 'Command line tools': start 'ccx' for Calculix solver & 'cgx' for pre-post GUI /opt/calculix - Documentation in /opt/calculix/doc

- Examples in /opt/calculix/example

- mesh converter from Salome:

/opt/helpers/unv2abaqus.py
GMSH Scriptable & general purpose geometry modelling, meshing and post processing use shortcut on desktop & start menu, or type 'gmsh' from 'Command line tools console' /opt/aster/outils/
gmsh
- tutorials & demos in installation directory
Gerris flow solver 2D / 3D  CFD solvers based on automatic octree mesh refinement use from 'Command line tools' console:
gerris2D, gerris3D, gfsview2D, gfsview3D etc..
/opt/gerris - examples & tests in installation directory
GraphiteOne 2D & 3D CAD system start 'graphiteone' from a console /usr/bin Free for personnal use, but not an 100% open-source package !!

Installing & upgrading CAELinux

Thanks to the very simple PCLinuxOS installer, you can very quickly turn your LiveDVD based CAELinux environment to a full featured hard disk install which will let you customize and update your system as you may want. We will not detail the installation steps here, but we highly recommend that you read the documentation on the PCLinuxOS Wiki section at http://www.pclinuxos.com. To install CAELinux Beta 3 on hard disk, you will need at least 10Gb of free space on an ext3 partition and preferably 1Gb on a Linux Swap partition (use PCLinuxOS disk partitionning tool to resize or create your partitions & BACKUP your data FIRST).


After installation, you will be able to customize your OS, install new packages & update your system (kernel, 3D drivers etc...) with the very efficient PCLinuxOS Control Center (in Menu->Configuration). From there, you will be able to configure all the aspects of the system and directly install & update softwares from Internet with the Synaptics software package manager.


For more information about the OS, drivers, kernel, etc.. please visit http://www.pclinuxos.com
