This work flow makes you to control fragment easier.
This basic example expresses of making of particles from center point of the chunks then particles control chunks, and then you can import them to dop and RBD objects follow particle motion moreover you can change chunks motion particle move to RBD simulation at any timing you want.
SOP
Expressions might be needed to make Fragments set up
Pick group by copy number
Copy number by number of the group
If you want primitives to take over particle attributes at copy node, check Use Template Points Attribute and to Primitive and add should be *
And you should convert primitive attributes from before DOP import node.
OUT_Geo should be center and particle for copy will be at center(not for OUT-POINT). Use Point Node and offset position by $TX - $TX2, $TY-$TY2, $TZ-$TZ2
As alternate way, you can set center point for each piece in For Each and then divide pieces and center points.

attribute_trigger(when contacting, it will return 1 just at the time) <option
group_trigger(for just to convert trigger attr to group) <option
attribute_inSim(after contacting, it will return 1)
Attribute_launchT(record simulation starttime) <option
Attribute_counter(counting time after simulation starts) <option

If you want to use Voronoi Fracture Solver, Rigid Body Solver doesn't work on the process.
Don't use rigid body solver. It doesn't work.
