Klaus Thoeni proposed the following answer:
Hi,

you are using randomDensePack to generate your assembly. The function
uses TriaxialTest [1] so the packing you get is most certain not stress-
free, i.e., particles will have overlap, hence you get an explosion.
This should be the case for spheres and clumps. Try using makeCloud [2]
instead or make your dense sample stress-free by shrinking the spheres
which overlap.
