Although significantly delayed, CAELinux  is proud to release its new stable version of CAELinux, named CAELinux 2013.


This release is built on an updated Xubuntu 12.04 LTS  64 bit base with a focus on the upgrade of the CAE softwares, development of additionnal Wizards and expanding the capabilities of the distribution to encompass the full cycle of a product development, including 3D printing, CAM / g-code generation,  electronic PCB design and even micro controller programming. CAELinux 2013 is now an even more complete open source engineering platform !

CAELinux 2013 contains updated versions of the Salome_Meca 2013.1 and Code-Aster STA11.3  FEA suite with MPI parallelism solvers, OpenFOAM 2.1.1 integrated with Helyx-OS or Discretizer GUI for settings up your CFD simulations (OpenFOAM 1.6ext is available in the repositories), Code-Saturne 3.0 MPI with a simple wizard GUI to get started easily, Calculix 2.6 FEA Multithread version with its own wizard, ElmerFEM 6.2 with high performance MPI solvers, the latest version of Freecad parametric CAD modeler, a custom PyCAM 0.6 release for 3D milling g-code generation with OpenSCAM for milling simulation, Cura for easy and fast 3D printing g-code generation, GEDA and Kicad electric design suites with many tools for PCB isolation milling and finally the famous Arduino microcontroller development environment.

With these software, Open-Source engineering is continuing its progression towards ease of use, completeness and  gets closer to commercial codes!


  • CAELinux is an installable LiveDVD Linux distribution based on Ubuntu 12.04 LTS 64 bit: a very user-friendly live Linux distribution, with excellent hardware detection and a very simple hard disk installer. The new XFCE desktop environment has been significantly customized to reflect the previous Gnome 2 desktop behaviour so that the transition is as smooth as possible for current users.
  • Contains the following CAE softwares:
    • CAE Pre-post processors: Salome_Meca 2013.1 i.e Salome 6.6, GMSH 2.5, Netgen 4.9, Tetgen, ElmerGUI 6.2, enGrid 1.4, Helyx-OS, Discretizer / Discretizer::Setup, Paraview 3.10, CGX 2.6
    • CAD-CAM: LibreCad,  SagCad, FreeCAD 0.13, Salome 6.6, Meshlab, Blender, OpenSCAD, PyCAM 0.6, GCAM, Dxf2Gcode, Inkscape Gcodetools, cadpy, Cura
    • Finite Element solvers: Code_Aster STA11.3 MPI, Elmer v6.2 MPI, Calculix 2.6 MT, Impact FEM MPI 
    • Computationnal Fluid Dynamics: OpenFOAM v2.1.1 and Code-Saturne 3.0 both with CFD analysis wizard and tutorials , Elmer FEM Solver,  Gerris flow solver, Javafoil, Javaprop and XFLR5 air foil, propelers and airplane analysis tools.
    • Multibody dynamics : MBDyn with its Blender interface
    • Electronics: GEDA suite, Kicad, Fritzing, Arduino, dxf2gcode & cadpy for isolation milling
    • 3D bio-medical image processing:  ITK-Snap with user filters, Image J, Voxel_Mesher
    • Mathematics &  programming : GNU Octave + QtOctave, Scilab, wxMaxima, R & Rkward, Python Scipy and Spyder, QT Creator, gcc, gfortran, g++, perl, python, ruby compilers/interpreters, Arduino 1.0 IDE
    • Document , graphics & office: Gnuplot, Latex, Lyx, Texmaker, g3data, Inkscape, Gimp, LibreOffice, Jabref.
  • Is provided with video tutorials as well as examples to start learning how to use the included open-source softwares for realistic simulation
  • Ubuntu 12.04 already includes open-source 3D drivers for most of the video cards, but it can also automatically install packages for 3D accelerated proprietary video drivers (ATI & NVidia cards) once installed on hard disk. For latest GPU and optimal performance, installation of proprietary AMD or NVidia drivers is however recommended after installation on hard disk.
  • This new release is available as a LiveDVD ISO image to use directly from DVD, to be installed to USB Flash disk or to install the CAELinux OS on your computer for optimum performance. On recent CPUs with hardware virtualization extensions, it runs also very well in Virtual Machine software like VirtualBox (it includes already VirtualBox additions v4.3.8) or VMWare.
  • A virtual machine image is available on Amazon Cloud Computing EC2 platform for both standard instances and cluster computer instances in Europe and US-East regions, see this thread on the forum for more information
  • This new release can be safely updated as any other Ubuntu install. All custom software is installed through packages hosted on our repository and can thus be automatically updated as any regular software.

CAELinux 2013 LiveDVD


CAELinux 2013 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 i3, i5, i7 and XEON 64 bit or AMD Athlon 64, Athlon X2, Athlon FX, Phenom, and Opteron. Please note that most Intel CoreDuo (not Core2Duo), Atom 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 minimum of 1024Mb is recommended to use this distribution for simple analysis and hardware compatibility testing. For optimal performance it is however recommended to create a Linux swap partition on one hard disk or even better to install the distribution to hard disk. For professionnal use at least 4Gb of RAM (more is better) is highly recommended for every day work. An hard-disk installation of CAELinux 2013 requires at least a 20Gb ext3/4 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 the latest  graphics adapters and some 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 prompt, Press ENTER and then a boot menu will appear 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 XFCE 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).
  7. 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).
  8. If you are happy with the distribution, you can then install it to hard disk. The installer can even resize Windows or Linux partitions to free up some space and install CAELinux in parallel to your existing OS.


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
