A great Linux distribution designed specifically for computer aided engineering. Based on the open-source CAE softwares Salomé, Code_Aster, Code_Saturne, OpenFOAM and Elmer .



Elmer is an open source multiphysical simulation software developed by CSC - IT Center for Science (CSC). Elmer development was started 1995 in collaboration with Finnish Universities, research institutes and industry. Elmer includes physical models of fluid dynamics, structural mechanics, electromagnetics, heat transfer and acoustics, for example. These are described by partial differential equations which Elmer solves by the Finite Element Method (FEM).



By EDF Group. Code_Aster is a general purpose FEA code. Code_Aster and SALOME is highly integrated through the Salome-Meca platform. It has the ability to solve problems in non-linear thermo-mechanics, coupled fluid-structure dynamics, sismic/non-linear explicit dynamics, contacts, and visco-plasticity.




By EDF Group. Code_Saturne is a general purpose Computational Fluid Dynamics (CFD) software. The basic capabilities of Code_Saturne enable the handling of either incompressible or expandable flows with or without heat transfer and turbulence. Dedicated modules are available for specific physics such as radiative heat transfer, combustion (gas, coal, heavy fuel oil, ...), magneto-hydrodynamics, compressible flows, two-phase flows (Euler-Lagrange approach with two-way coupling), or atmospheric flows.



By Kitware. ParaView is an open-source, multi-platform data analysis and visualization application. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. The data exploration can be done interactively in 3D or programmatically using ParaView's batch processing capabilities. ParaView was developed to analyze extremely large datasets using distributed memory computing resources. It can be run on supercomputers to analyze datasets of terascale as well as on laptops for smaller data.



By The OpenFOAM Foundation. The OpenFOAM® (Open Field Operation and Manipulation) CFD Toolbox is a free, open source CFD software package. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics. It includes tools for meshing, notably snappyHexMesh, a parallelised mesher for complex CAD geometries, and for pre- and post-processing. Almost everything (including meshing, and pre- and post-processing) runs in parallel as standard, enabling users to take full advantage of computer hardware at their disposal.



By OPEN CASCADE SAS. SALOME and Code_Aster is highly integrated through the Salome-Meca platform. SALOME is an open-source software that provides a generic platform for Pre- and Post-Processing for numerical simulation. It is based on an open and flexible architecture made of reusable components. SALOME is a cross-platform solution. It is distributed as open-source software under the terms of the GNU LGPL license. You can download both the source code and the executables from this site. SALOME can be used as standalone application for generation of CAD models, their preparation for numerical calculations and post-processing of the calculation results. SALOME can also be used as a platform for integration of the external third-party numerical codes to produce a new application for the full life-cycle management of CAD models.



Scilab is free and open source software for numerical computation providing a powerful computing environment for engineering and scientific applications. Scilab includes hundreds of mathematical functions. It has a high level programming language allowing access to advanced data structures, 2-D and 3-D graphical functions. A large number of functionalities is included in Scilab: control, simulation, optimization, signal processing... Xcos, the hybrid dynamic systems modeler and simulator is provided with the platform. Scilab is free software distributed under CeCILL license (GPL compatible). It comes with source code, help and English user manuals. The availability of source code is of great interest in research or for strategic applications. The distribution mode of Scilab is particularly well suited for education where students can receive a free copy or as a tool for scientific cooperation without constraints. The international scientific community, both academic and industrial spheres, invests in Scilab. Many external modules, contributions from users or from the Scilab Consortium R&D team, can also be downloaded.
