After nearly one year of development, we are proud to release our new stable version of CAELinux, called CAELinux 2009. This release is a complete rebuild of CAELinux for X86 64 bit architecture of the latest Intel / AMD cpus. CAELinux 2009 is now based on one of the most popular linux distribution: Ubuntu and thus contains many enhancements, new softwares and should give you in the end a much better user experience.

CAELinux 2009 is built on the basis of Ubuntu 8.04 LTS 64bit distribution with the latest updates and should support the most recent hardwares / chipset for one of the best compatibility and ease of use in the Linux world. It comes with a  kernel in version 2.6.24-24 with support  for 64 bit memory addressing  and  multiple CPUs.

Additionnally, CAELinux 2009 contains the new release of the GPL Salome_Meca 2009 package developed by EDF (32bit) integrated with an optimized 64bit installation of Code-Aster STA 9.4 with OpenMP support. This updated package represents the fusion of a powerfull Code-Aster STA9.4 finite element solver and the Salome  v4.1.4 CAD/Pre/Post GUI and allows to run a complete FEA study directly from the SALOME graphical user interface.

CAELinux 2009 also continues to integrate great open source CFD software like Code-Saturne 1.4 and OpenFOAM 1.5 that can be both interfaced with numerous pre processing tools like Salome, GMSH, Netgen, and the brand new CFD oriented mesher enGrid 1.0. With these software, Open-Source FEA & CFD is continuing its progression towards ease of use and parallel computing power to get closer to commercial FEA & CFD codes!

  • This new release is only available as a LiveDVD ISO image to use directly or to install the CAELinux OS on your computer for optimum performance.

CAELinux 2009 LiveDVD


CAELinux 2009 is only available in 64bit version, this means that you will absolutelly need an X86_64 compatible CPU to run this version. Most recent Intel and AMD CPUS are 64 bit : for example Intel Core2Duo or Core2Quad, Core i7 and XEON 64 bit or AMD Athlon 64, Athlon X2, Athlon FX, Phenom, and Opteron. Please note that most Intel CoreDuo (not Core2Duo) and Pentium 4 are NOT 64 bit compatible! Please check your hardware compatibilty first!! Using a 64 bit OS is necessary to use more than 2Gb RAM per application and thus allows for large "industrial scale" simulation capabilities. If your CPU is not 64 bit, you can still use our previous release CAELinux 2008 which is available in both LiveDVD and VMWare virtual machine version: see this page for more information on CAELinux 2008.

This LiveDVD distribution is highly compressed on the DVD and requires that the system decompresses all the necessary softwares into RAM in order to run. In LiveDVD mode, a strict minimum of 512Mb is required to use this distribution for simple FE analysis. But you can create a Linux swap partition on one hard disk to help or choose the option to install the distribution to hard disk for optimal performance. However, 2Gb of RAM (or more) is highly recommended for every day work. An hard-disk installation of CAELinux 2009 requires at least a 20Gb ext3 partition for "/" and a 4Gb swap partition. At the moment most of the classical chipsets for Intel and AMD platforms are supported with some exceptions especially concerning external USB modems, specific laptop devices (some wireless network cards) and very specific hardware like Raid controllers. For more help on hardware support / detection / troubleshooting, you should refer to the great Ubuntu documentation, wikis and  forums :


  1. First, download the ISO image from the link below. Then you should check the md5sum of your downloaded file to check if it is not corrupt: in Linux, use the "md5sum" command in a console, in Windows, you should download the "md5sum.exe" command line utility from here.
  2. Burn the ISO image on a DVD+/-R/RW with your favorite DVD burner software. Be sure to select the "Burn Image" option in your DVD burning software. If unsure, read the help of your DVD burning software. Alternativelly, you can install the LiveDVD on a USB key with the simple and efficient tool UNetBootin available here:
  3. Read the "Ubuntu Installation Manual " and associated documentation at
  4. Restart your PC, insert the LiveDVD (or USB key) and verify that your BIOS is configured to boot from CD/DVD drive (resp. USB external drive).
  5. Boot from the LiveDVD: you will see a boot menu with several options. Usually you don't need to select any special option here but if you have some problems during the boot process, some alternative options can be selected. For the moment, just press "Enter" to accept the default mode.
  6. When the boot process is finished, you will need to login with the following account:
    login = caelinux , password = caelinux    
  7. When the GNOME desktop is finally loaded, you can start your work as if you were running from an hard disk. Note that all the readable partitions of your HDD will be allready accessible and your USB key or external HDD will be recognized when you plugin it in (read-write access).
  8. Now you can start your first tutorial on FE modelling with Salome_Meca: just click the "GettingStared" link on the desktop and follow the first tutorial on the FE analysis of a 2-stroke engine piston (from a STEP CAD geometry).


For the moment, a first documentation is available in the GettingStart.html  & "Ubuntu Installation Manual "  file included in the distribution. Several tutorials, videos and examples are included on the distribution and also downloadable on the wiki
