Sample animations from simulations I've done:
Simulated N-body horseshoe orbit of solar system moons Janus and Epimetheus. The co-moving reference frame is chosen so that one of the moons is always located at the top of the image, despite the fact that both moons are orbiting Saturn (center).
2D Athena simulation of a the inviscid hydrodynamic Rayleigh-Taylor instability. Density contrast=2.
2D Athena simulation of a viscous hydrodynamic jet. Jet speed is half of the ambient sound speed.
2D Athena simulation of an inviscid hydrodynamic jet. Jet speed is half of the ambient sound speed.
2D Athena simulation of a the inviscid hydrodynamic Kelvin-Helmholtz instability. Flow speed is half of the fluid sound speed.
3D MHD Athena simulation of the Kelvin-Helmholtz instability.
3D MHD Athena simulation of an unstable plasma column. (O'Neill, Beckwith, & Begelman, 2012, MNRAS, 422, 2, 1436-1452.)
3D MHD ZEUS-MP simulation of the reaction of a circumbinary accretion disk to a black hole binary merger. (O'Neill, Miller, Bogdanović, Reynolds, & Schnittman, ApJ, 700, 1, 859-871.)
3D MHD ZEUS-MP simulation of the innermost regions of a black hole accretion disk. (O'Neill, Reynolds, Miller, & Sorathia, 2011, ApJ, 736, 2 , 107-113.)
3D MHD Simulation of a Narrow-Angle Tail Radio Galaxy.
3D MHD Simulation of Intermittent AGN Jets Propagating Through the Intracluster Medium. (O'Neill & Jones, 2010, ApJ, 710, 1, 180-196.)
