Question #270991 on Yade changed:
https://answers.launchpad.net/yade/+question/270991

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Behzad,

as usual, more options are available :-) for example

1) have a look at [1], you can create a predicate for each clump and
"subtract" them from original predicate. I am not sure with the
performance..

2) create the packing as you described and delete the standalone spheres
that interact with clumps

cheers
Jan

PS: a MWE [2] with the commands you are using would not hurt anyway :-)

> Some spheres are completely inside a clump and number of spheres and
