Does it exist a (simple) way to create a boolean between two meshes ?

Hello everybody,

For my school project I have to use Salome Meca, and I never used the software before .This is my first comment on this forum, I made some researches and i didn't find what i want. If the answer already exists i haven't seen it.

Here is my issue : I have two 3D meshes which cross each others. In my project i need to create the form of the smaller object in the bigger one. See the file attached below. I have to subtract the external shape of the smaller object to the bigger one.

Plus i don't know Python, so if the answer is easy it would really help !

Thank you all

Thomas
