Have you tried the RBDautofreeze tool? I don't know if it will speed up
your sim but it should bring it to rest at least.

Subject: [Sidefx-houdini-list] reducing dops simulation time
I was wondering if anybody had any useful tips for reducing dops
simulation times. My dops simulation is actually pretty straight
forward. I have a bunch on spheres that move around and interact with
one another. They never stop moving. One optimization I found was the
"implicit sphere" for the sdf representation. Another is "sphere" for
the culling method in the rbd options. Other than that, I'm kinda stuck.
Dops doesn't seem to do sdf->sdf collision detection that I know of. So
each point in the sphere with the sdf of nearby spheres. With the
potential of thousands of spheres, my simulation times are becoming
unworkable. Seems like there should be a built-in optimization for using
spheres since collision detection between spheres is pretty
thanks for any suggestions.
