Draft:Code aster

Presentation

Code aster

Code_aster is a free and open-source software for numerical simulation in structural mechanics, developed mainly by the Electrotechnics and Structural Mechanics (ERMES) department of EDF’s Research and Development division.

ASTER stands for “Analyses of Structures and Thermomechanics for Studies and Research”. It is a complex software package whose development began in 1989 to meet EDF’s internal needs. It was released under the GNU GPL license in October 2001.

The core of the system is written in Fortran, and many additional modules are developed in Python. The codebase contains more than one million lines, numerous test cases, and extensive documentation.

Stabilized versions are released roughly twice a year as source packages to be compiled. These releases can be updated weekly to track the latest development version.

It is primarily a solver, based on continuum mechanics theory, that uses the finite element method to solve various types of mechanical, thermal, acoustic, seismic, and other problems.

Its source code can be freely downloaded from the project website, which also provides the Salome-Meca package containing the official, universal binary versions for Linux. Some Linux distributions also offer binary packages. Several Windows binary versions are available, with almost the same features as the Linux/Unix versions. There is also the CAE Linux LiveDVD, dedicated to CAD and including Code_Aster.

Features

Code_Aster is a general-purpose software for simulation in mechanics and structural analysis. In addition to the standard functions of a thermo-mechanical simulation tool, Code_Aster includes numerous constitutive laws, finite element methods, and loading types.

The Salome-Meca module of the open-source Salome platform provides an intuitive graphical interface for setting up a study. Salome enables users to carry out CAD preparation, meshing, and Code_Aster analysis within a single environment through its modules. The graphical interface of Salome-Meca offers interactive mesh visualization, making it easier during study setup to configure the geometry of the system of interest (displaying groups on which mechanical constraints must be applied, or parts of the mesh that must be fixed, etc.).
