I'm just learning the rigid bodies for the first time and I'm doing the quickstart tutorial on the SideFX website. There are a bunch of columns and they get hit by a swinging pendulum and break apart. The problem is when I run the sim the columns start to break all on their own without being hit by the pendulum. How can I get the columns to stay unbroken until they are hit?

This question comes up so many times . I wish the search engine for this site was better.
Flick the rbd solver engine from bullet to RBD in the dopnetwork . Then read up in the help on concave and convex geometry and you will see why the geometry flies apart

I have a node called AutoDopNetwork but I can't seem to find anything that says bullet. Where do I find the solver choices?

Dive inside and find the rbd solver dop

Thank you sir! I found it and it worked..
