Salome-Meca & Code_Aster

Use the open source simulation environment Salome-Meca to master your daily challenges in product development.

Salome-Meca combines the pre- and post-processor Salome and the powerful FE solver Code_Aster in one simulation environment. The software has been developed by the French energy supplier Életricité de France SA (EDF) since 1989 and was then released as open source software in 1999 under the terms of the “General Public License”. That means: You can use Salome-Meca commercially without any restrictions!

Salome-Meca is used by EDF for the analysis of highly safety-critical components in nuclear power plants and must therefore meet high safety standards. For this purpose, the software is regularly verified and validated with over 5,000 benchmarks. A team of around 50 engineers is constantly working on further development. An update is made available every year. The range of applications extends from classic non-linear solid mechanics through thermal analyzes to the special fields of acoustics. Salome-Meca can run on Windows and Linux.

Frequently asked Questions:

How can individual tutoring be ensured during a webinar?

In our opinion, until recently there was no technical solution to supervise the important exercise phases in the context of our seminars with the same quality during a webinar. This is mainly due to the fact that with the classic software solutions (zoom, teams etc.) we can only address the entire group at the same time. This makes individual exercise supervision impossible, and networking and professional exchange are out of the question.

However, the corona pandemic has driven digitization. A Berlin start-up has a new software called WONDER developed which meets the contemporary requirements. This software can be used to give a presentation to a large group, such as teams. In addition, in the large group, small sub-groups can come together for individual discussions. Exactly this function is ingenious and enables us as lecturers to virtually walk through the rows of the seminar room during the exercise phases and help each participant individually. This enables us to ensure the high quality of our exercise support in webinars as well.

We also have the option of setting up a virtual coffee corner. This enables a lively professional exchange!

    Where can I find out more about the open source simulation software Salome-Meca (Code_Aster) and download it?

    Salome-Meca can run on Windows and Linux. In addition to the Windows version, you can also operate the Linux version with a virtual machine under Windows. Which of the three approaches is the best depends on your computer and your individual needs. After booking the seminar, we will support you with the installation and will also be happy to advise you.

    You can find all details on the official Code_Aster website:

    Link to the official website of Salome-Meca (Code_Aster).

    Link to the Windows version.

    Which system requirements does my computer have to meet?

    To solve implicit systems of equations in the context of finite element analysis, in particular, sufficient working memory is required. Our experience is that (4-8) GB of RAM is completely sufficient for training and initial small simulation projects. If you have a laptop or desktop PC with (4-8) GB of RAM that is otherwise state-of-the-art, that is completely sufficient. The computer must have Windows or Linux as the operating system.

    Will the webinar address my individual, company-specific questions and challenges?

    We love to discuss their individual issues with our seminar participants. We support every participant in applying the knowledge they have acquired to these company-specific issues.

    If the webinar ends at 5:00 p.m., we will be available to all seminar participants until all individual questions have been clarified. On the last day of the webinar we planned a complex exercise. This only aims at developing and testing simulation strategies for your individual questions.

    As a rule, every participant leaves our webinar with a clear simulation strategy for their company-specific questions.

    Where can I get help if I get stuck after the webinar?

    We will be happy to support you after the webinar. You can book a support voucher for this and call up the hours it contains within a year as required. Our support includes not only the software application but all topics related to “simulation in product development”.

    If you would like to tackle a completely new and challenging simulation project and do not have the time or inclination to acquire the necessary know-how self-taught, you can book a company-specific special training course with us.

    If you are interested, just speak to me.

    Is it time consuming, annoying and difficult to install open source software?

    There is one Windows and a Linux version from Salome-Meca . To install the Windows version, all you have to do is download and unzip a ZIP folder. The software can then be started directly. A single command needs to be entered into the terminal to install the Linux version. This is provided on the download page.

    Is open source simulation software difficult to use and does it require programming skills?

    The user interface of Salome_Meca is completely graphical and can be operated intuitively after a short training period . Our training courses are mainly attended by designers and development engineers from small and medium-sized companies. Almost all participants can build simulation models on their own after the first day, even though they do not have any programming skills.

    Is the range of functions of open source simulation software limited and not extensive enough for industrial use? Is it worth training if more complex issues have to be switched to commercial software anyway?

    I have been working with the open source simulation software Salome-Meca since 2012. During this time I used Salome-Meca in particular for virtual product development and product and process optimization in small and medium-sized industrial companies. From normal strength calculations and forming simulations to topology optimization, I have solved all my customers’ questions with open source simulation software. I think this is a meaningful field test that refutes this prejudice!

    Does open source simulation software deliver valid results? Can it be used for the preparation of, for example, verifiable strength reports?

    The open source FE solver Code_Aster is implemented in Salome-Meca. Code_Aster was developed by EDF for the design of nuclear power plants. Code_Aster is developed by a team of around 50 simulation experts. Each new version is validated with over 5,000 benchmark tests before it is released. My experience with strength reports for pressure equipment is that the software is accepted by all relevant test centers (e.g. TÜV) without any complaints.

    Commercial programs have interfaces that can be used to import components from CAD programs. Does this also exist with open source software?

    Salome-Meca has various interfaces for importing and exporting 3D CAD data, above all STEP, IGES, STL.

    Commercial programs have training, support, and extensive user manuals. Am I on my own when using open source simulation software?

    There is a very extensive user manual for Salome-Meca. In addition, there is a great deal of high-quality, but free, teaching material for open source simulation software. For Salome-Meca, for example, there are many YouTube tutorials and even a free book. If you need to move forward quickly, you can attend our training courses and take advantage of our support. Of course this is chargeable, but it is also with commercial software. With commercial software, you bear the costs for training and support and also pay the license fees.
