An accurate and efficient code for following arbitrary (massive-particle) geodesic orbits has been developed. Preliminary results of applying the code to the evolution of relativistic stellar orbits around massive black holes in active galactic nuclei are presented. Particular problems being examined are the dynamics of star-accretion disk interactions in the relativistic regime and the evolution of dense star clusters in which stellar collisions dominate other interactions, which is treated using an N-body type of analysis.
