Effect of Gravity on secondary fracture

[Naeem]

Hi,

I am working on a simulation in which a pre-fractured geometry is fractured further upon impact. However, I want the gravity force to just affect the pieces created upon impact and not the entire RBD object. Any ideas on how I can achieve this?

put your new created chunks in a separate group and have a gravity DOP only affect this group, it's that easy

cheers,

essentially just put: * ^gear_front_face

into gravity group parameter

so the gravity will affect everything except gear_front_face object (assuming your DOP object is called like that node)

since all fractured pieces are named differently gear_front_face_<something> they will still be affected

Thanks Manu and Tomas

I saw that the fractureparms creates pieces as ${OS}_new_pieces so I was trying to specify that in the group mask of the Gravity DOP. Didn't work as expected. I'll try what you've suggested. Thanks again.
