Hello Cesar,
Did you find an answer to your question? I have the same question. I installed Salome 9.12 from Salome-platform website, but it does not have code aster environment in it. I searched the documentation(Add/remove modules dynamically — GUI 9.12.0 documentation) and it said Click on ADD modules icon.
But my Salome installation does not have the ADD MODULE button at all.
How do I install MECA in my salome installation?
Do I download Code Aster from Download - Code_Aster and somehow add it to my Salome Installation?
(or)
Do I HAVE to download Salome Meca directly from Salome-Meca - Code_Aster?
If I download code aster from the first link, how do I add it to my Salome installation?
If I download Salome Meca directly, how do I know which version of Salome I am getting in it? I would like to have the latest version of Salome.
