How volume intersections are interpreted in Feko?


Updated by Altair Forum User
As i know, if two volumes intersect in Feko, i have to cut one from another, then create the one i cutted once again and unite them with unity.
I create 1000 Spheres, some of them intersect. What would be right in Feko?
Can i go through each Sphere i add and cut it from previous cubes and then add them as unity, even if they dont intersect
or
Is it needed to determine Volume Intersections generically and only in this case cut the one volume, then create it again and unite
How can I detect volume intersection in Feko? or I should better add a Matlab Scipt for determining intersections?
