Jan Stránský proposed the following answer:
Hello,
> I want to then be able to change a particular sphere radius
for b in O.bodies:
b.shape.radius = whatever # there is a function also modifying mass, but I
cannot find it just now
> let the system "attract" into its centroid to recreate a dense packing
with the newly sized particles.
maybe [1]? (never used it myself..). Before using such approach, probably you
would need something like
for b in O.bodies:
b.state.pos = O.cell.wrap(b.state.pos)
cheers
