i want to give name selection to design I have attached. in name selection I want to give porous name to all spheres and domain to the remaining(excluding all spheres) part.
this task I want to do using script in spaceclaim
anyone can help me please

    i have written the above code but only one sphere is selecting in porous medium

    I thing it is happening because of all spheres are not intersecting with cube so can you provide me the code how to intersect the spheres and cube
