Eficas is an editor for Aster’s command files. It can intuitively prepare an Aster’s command file without prior knowledge of Aster’s command syntax.

Warning: Each version of Eficas is adapted to a particular version of Code_Aster. For instance Eficas 7.8.0 for Code_Aster version 13.3.

See also this page for a modified branch, for use in Code_Aster.


METIS was developed by George Karypis, University of Minnesota. It is a group of tools (including one for mesh partitioning). Aster is used in the renumbering algorithm only.

Version used: 5.1.0

MED and HDF5 libraries

MED is the Data Echange Module used by Code_Aster and based on the HDF library.

  • MED/HDF can read and save data in a format which is portable between machines of different architectures.
  • They are required during Code_Aster compiling.

MED is distributed under LGPL license. The sources are available here.

Version used: 3.2.0


The Homard software adapts 2D/3D meshes for finite elements thanks to refinement and unrefinement.

Version used: 11.7

See HOMARD website.


Soil-Structure Interactions (ISS) and Sol-Fluid-Structure (ISFS) involved in buildings dynamics or in arch dams, can be resolved with frequency coupling in Code_Aster.

MISS3D (called via the Code_Aster command CALC_MISS) is a code with integral equations (Green functions) and sub-structuring from ECP / LMSSMat .

Kept and provided for compatibility reasons

GIBI is the mesh part of CAST3M. Code_Aster can read mesh files from GIBI and produces results for a post-processing in GIBI.

Compatible version: 2000

The license concluded between end-users and the French Atomic Energy Commission (CEA) enables the users to freely use GIBI with Code_Aster. For further information please read the README file.
