As I see it, calm will not help a lot because it is the size of the
periodic box itself that is bouncing too much, while calm will only calm
down particles. In your commited version at least, the problem is still
there.
The real problem is the huge overlap between clumps after random generation.

I fixed it by setting a max number of particles and a smaller size of
clumps (last commit). Isn't there a better way than trial and error to
get the appropriate clump size? Did you ever generate a non-overlaping
clump cloud?

I was in fact surprised that makeClumpCloud doesn't complain on
overlaps. If it was following the model of makeCloud, it would not give
any overlap, but apparently it is not checked in the clump version (or a
bug in the periodic case?).
