How to do Splitting of multiple Volumes in one go
 

Hi all
I am work on CFD analysis of pebble bed reactor .Basically pebble bed reactor consists of random arrangement of spheres in a canister(Rectangular). I have created the geometry for the same and meshing in Gambit . I need to split the spheres from the main canister. Since there are more than 1000 spheres in my domain it is very hard to do it manually Is there a way that i can do multiple volume splitting in one go.
Thanks in advance for help
