Did you know that Code_Aster was originally developed for structural calculation?
I got several requests for a “Beam Tutorial” in the past weeks since I recorded the previous video tutorial of a simple plate analysis… So here it is finally!
How to simulate a beam in Salome Meca 2017?
In the video, I show you how to create a simple beam geometry, how to mesh it and how to create the analysis case using the new Aster Study included in Salome Meca 2017.
So here’s the video:
Documentation for beam section in Code Aster:

Documentation of beam elements formulation in Code Aster:

I tried to make the analysis quick to show the most important points first, but in case you see something to improve, please do not hesitate to leave a comment!

In addition to the effort Cyprian does for showing us and teaching us Salome-Meca, I found a useful reference (e-book) that is free to download: https://www.free-ebooks.net/ebook/Finite-Element-Analysis-Salome-Meca-Code-Aster.
All the credits go to the authors: Syllignakis Stefanos and Petr Vosynek.
thank you
Hi Cyprien
Thanks a lot for the video and for the explanations. Well despite all your efforts my analysis didnt run well and ended up with an error message, I must have made something in a wrong way. I would like to ask if it is possible to share the command file what you exported (maybe for all the models?? :) ). Usually the best and fastest way to find a problem is to go through the command file but at the very beginning I do not know what I am searching for, so if I could compare my command file to yours I would maybe spot the mistake within a few minutes meanwhile my eyes would get used to the system of commands.
Thanks and have a good day!
Hi All,
I don’t know if someone need it, but to view the beam in a deformed shape you need to apply the Warp by vector filter (filter-common-warp by vector)
Have a nice day

Hi Cyprien,
How to define the unit system in Salome Meca? Sometimes meter is used, sometimes millimeter is used. I’m really confused.
So the easiest way is to use all units in SI units. That way the distance unit will be meter.
If you choose to use a non-SI unit like millimeter for example, you can, but you will have to scale appropriately all other units which include a distance unit in them. For Example in SI, 1 Pascal (Pa) is equivalent to 1 N/m2. If you choose mm, then all your pressure units will now be in N/mm2.
