Code_Aster has been developed under the leadership of EDF (Électricité de France) R&D since 1989. It is developed mainly for Unix and is distributed under the GPL licence. Some ports exist for Microsoft Windows (ref).

Code_Aster itself has no GUI but it comes with two GUI applications: astk, a management and control interface (document U1.04.00), including eficas, a command-file editor; and STANLEY, a post-processor (document U4.81.31). Code_Aster can also be used within Salome-Meca, which is a bundle of Code_Aster with Salome. The latter is a cross-platform, open-source, generic pre- and post-processor for numerical simulation, which can be used by itself or as a ‘platform for integration’. ParaView is integrated into Salome as the ParaViS module.

Very extensive documentation (~20 000 pages) and training material is available on the Code_Aster Web site. It is written in French and the English version is translated by machine.

Beginning with Code_Aster by Jean-Pierre Aubry (local copies of 2013 and 2019 editions) is in English, and includes the use of Gmsh and (to a much lesser extent in the 2019 edition) Salome.

The student-produced documentation by Syllignakis (supervised by Vosynek) and these tutorials may also be useful.

There is an active forum.

Use with Fad

Our Fad finite-element preprocessor can export .mail files and primitive .comm files for use with Code_Aster.

Note that Code_Aster's .med files are binary files in HDF format; they can be manipulated using the tools in the Debian hdf5-tools package. Fad cannot currently import or export .med files, but it can import the .dat geometry files that Salome-Meca can export.




[2015 Apr] Download aster-full-src-11.7.0-1.noarch.tar.gz (or an equivalent) from Use gunzip and tar to unpack the downloaded file. Read the README file. Follow the various links for information about the different versions and about prerequisite software, including Installation of prerequisites wiki page. (In addition to the things listed there, the installer checks for a number of other things, many of which are probably installed in most cases. In my case, the following are still flagged as missing: nedit, geany, gvim, gdb, dbx, ladebug & cmake.) Use Python to start the installation.

If installing in the directory recommended by Aubry, do sudo mkdir /opt/aster/ and sudo chown username:username /opt/aster. Or specify a user directory with --prefix.

Packages libblas-dev and liblapack-dev are needed.


[2011 Jan] Download SALOME-MECA-2010.2-LGPL-x86_64.tgz (or an equivalent) from ▶ Download ▶ Salome-Meca to, say, ~/Downloads64/. Do

    tar xzf SALOME-MECA-2010.2-LGPL-x86_64.tgz
    cd SALOME-MECA-2010.2-LGPL-x86_64/postinstall
You may receive warnings about DSCCODE GUI and PAL GUI resources; I don't know what they mean, and so far they don't seem to have caused problems. Run Salome-Meca with the runSalomeMeca script in the installation directory. If you want to add it to the GNOME launch panel, specify the Type as Application in Terminal. The file icon_default.png in SALOME/SALOME5/V5_1_4/GUI_V5_1_4/share/salome/resources/gui/ makes a good icon.

The above procedure worked fine for me under Debian Lenny. Under Ubuntu Lucid, Salome-Meca runs but actual simulations die quietly without doing anything, apparently due to missing libraries.

Brief recipe

There are multiple ways of performing the following steps. I've shown the ‘long’ ways, using the menus, but often a judicious right-click or icon click can also be used.

Source code

Document D0.03.01 describes the general architecture of Code_Aster. The manual is dated 2010; even so, Section 4 on the execution supervisor starts by saying that it needs to be profoundly revised because the supervisor, written in Fortran, had a long time before been rewritten in Python and greatly extended.

The SRC directory contains 10 subdirectories:
