NOTE: In H16 the RBD Static Object has moved to the Collisions tab

SCALE MATTERS IN DYNAMICS! (Houdini measures in meters/kg/seconds - 1 unit is a meter (about 3 feet))

Check out the masterclasses on the bullet solver (H12)
H13 Masterclass - Bullet Solver with Cameron White

Also, if you have not done so already, go thru the documentation on dynamics. Be sure to include reading the "top ten" lists (see Subtopics/Learning Dynamics near the bottom of the page) that link to further pages.

There are clear instructions on caching simulations here (H13) and here (H16).

Also remember, if you want to use a number of objects, there is a similar node somewhat like the copy node - RBD point object - see the tips and tricks RBD section and jelly bean examples.

Proxy geometry can be very useful in speeding up your sim times.
(Example coming soon)

Try a simple solver:
create a sphere, inside the geometry container add a Solver node, connect the sphere as the first input and inside the solver add a transform node with 0 1 0 and connect it to Prev_Frame
