Christian Jakob proposed the following answer:
hi emon,

to [1]:

You can generate spheres and replace them via a clump template, example
see:

https://github.com/yade/trunk/blob/master/examples/clumps
/replaceByClumps-example.py

note: Equivalent radius of the clump = radius of the sphere before
replacement

to [2]:

clumps are ridig, not deformable, not breakable. you can release members
from the clumps "by hand" using releaseFromClump(), example see:

https://github.com/yade/trunk/blob/master/examples/clumps
/releaseFromClump-example.py

but i think you want to have bonds, that can break while stress exeeds certain limit, right?
therefore there is a nice contact law CPM:

http://yade-
dem.org/doc/yade.wrapper.html?highlight=cpm#yade.wrapper.CpmPhys

but i am not sure if you can create bonded (clump-like) particle
assemblies with CPM ...

hope it helps,

christian
