RBD glue constraint problems

[ForeverMovement]

Hello all, 

I'm trying to learn through RBD by doing a sim where a fence gets riddled with bullets. I have the basic sim in place and where I think it all should be but when I sim it just explodes anyway instead of holding together. 

Attached below is the scene file because I'm truly lost.

 

Thanks!

Try putting the Glue's strength = -1 (unbreakable). Then in the "Remove Broken" sop solver: attribute promote should use the "Maximum" method, the attrib wrangle should Run Over "Primitives" and instead of removing the primitive based on the Cd, you should put it in the broken group like this: @group_broken = 1;

It should works...

My god it does work, thank you! Now I just need to find a way to transfer the velocity attribute from those same impact points to the rbd sim itself, any ideas?
