EDIT: i would like to know also how to create angular velocity to transfer per piece

i am trying to orient manually normals to transfer them into point velocity for a choreographed RBD simulation.

Basically i create point clouds with uni directional normals, place them and rotate them accordingly to the direction i want the pieces to go, then transfer the normals onto my RBD fracture object.
Finally i vopsop normals into point velocities

it is working but i would like to know if there is a better/smarter way to do so.

here is an example file

thank you

There is many solution to drive explosion with DOPs. One of these are with a magnet force. You can find solution in this forum or odforce forum.

But for info, i modified your file. Modifications are in red.
And for angular forces, look at the Point SOP. There are a lot of tab to setup those forces.
