Hi Ricardo,

Please use one theme at a time (thread); otherwise, searching the forum or reading along is difficult. Thank you.

I am not aware of a connection among multiple Push Apart Effectors. But please suggest this here:
"Share Your Idea"

It sounds like a great idea, like a Push Apart with a List to pull Cloner Objects and Matrix Objects in a list and evaluate them all at once.

For now, this setup might help.

The idea of Instances is simple: calculate on Clone and have the data, not the object for the render engine.

Perhaps there is an idea to place the SDS as a parent on a Cloner, but if one could use the SDS on the Clone Child before it is Cloned, the SDS would have to deal with one object only, not with many.
In other words, if there is no urgent reason, SDS before Cloning. It will save you a lot of time.
If possible, use the
Mesh> Add> Subdivide * > Smooth ( the * means, use the cogwheel)

All the best
