[Gmsh] Include volumes into other a bigger volume GMSH

[Nicolas Bachelard]

Hi GMSH team,

I want to create a cube on which I should add spheres with random
positions.

I already have the GMSH functions to generate 3D spheres and the big
Cube where I want to include them.

Do you have an idea of how I could include my sphere at random positions
inside this cube?

Best regards
