Two clear objectives
A computational code developed through research and proven in industry
Developed by EDF R&D, code_aster is a mechanical and thermal simulation software package designed for structural analysis, research and assessment.
Designed to meet the needs of the most demanding industrial applications, it combines scientific innovation, a wealth of features and high-quality standards.
Today, code_aster represents:
- over 1 million lines of code;
- over 3,500 test cases run daily;
- over 23,000 pages of documentation; several decades of development and validation.
ㅤ
Who is code_aster for?
The ecosystem built around code_aster is aimed at engineers, experts and researchers involved in analysing the behaviour of structures and materials. Its development is supported by a network led by EDF R&D, bringing together industrial partners, engineering consultancies, universities and research laboratories.
ㅤ
Why use code_aster?
Numerical simulation is an essential tool for informing decisions regarding the design, operation, maintenance and service life extension of facilities. Its advanced mechanical and thermal modelling capabilities enable the behaviour of structures to be assessed, risks to be anticipated and the most demanding technical choices to be supported.
These capabilities are made available to users via Salomé-Meca, an integrated pre- and post-processing environment that facilitates the implementation of simulations and the analysis of results.
Overview of code_aster’s features
code_aster covers a wide range of mechanical and thermal simulations. It stands out in particular for its extensive range of constitutive models, finite elements and non-linear simulation capabilities.
Its area of excellence lies in non-linear simulations, particularly in the fields of civil engineering, fracture mechanics and geomaterials. It also offers advanced features for structural dynamics, thermo-mechanics, fluid-structure interactions, multiphysics couplings, sensitivity analysis and model recalibration.

Open-source software
Distributed under the GNU GPL licence, code_aster makes its source code, documentation and test cases freely available. This openness fosters industrial and academic collaboration, facilitates knowledge sharing and contributes to the continuous improvement of the software.
Today, code_aster is used in numerous industrial and scientific fields and benefits from ongoing development led by EDF R&D and its ecosystem of partners.
From code_aster to Salomé-Meca
code_aster’s computational capabilities are now accessible via Salomé-Meca. This development enables us to offer a comprehensive environment covering the entire simulation cycle, from model preparation to the analysis of results.
