This paper describes an approach for the dynamic simulation of complex
computer-aided engineering models where large collections of rigid bodies
interact mutually through millions of frictional contacts and bilateral me-
chanical constraints. Thanks to the massive parallelism available on to-
day's GPU boards, we are able to simulate sand, granular materials, and
other complex physical scenarios with one order of magnitude speedup when
compared to a sequential CPUbased implementation of the discussed algo-
rithms.
