  • H2 ortho/para equilibrium tests. Equatorial and meridional views of two simulations. The upper-left panel shows a disk that is evolved with the correct H2 internal energy for equilibrium ortho/para statistics. The upper-right panel shows a disk that is evolved with the assumption that the specific internal energy e = Cv T, where Cv is the specific heat at constant volume and T is the temperature. The lower panels are snapshots. The logarithmic color scale represents density, and the units for each axis are in AU. The counter indicates the number of rotations at 18 AU.
  • Test 4 for the Frontiers in Computational Astrophysics 2004 workshop. Equatorial and side views. Different hydrodynamic codes are used to run the same simulation for comparison purposes. The disk shown here is evolved for 15 code units.
  • Radiative Cooling without Irradiation. Equatorial and side views.
  • Shock waves. Radial slice of the forced-shock run described in Boley et al. (2005). The arrows represent relative gas velocities scaled to each axis appropriately. The black solid contours are density contours of 2.81(-12), 3.54(-10), 7.08(-10), 1.42(-9), 2.83(-9) g/cc. The thin red contours represent volumetric heating rates produced by shocks: 3.51(-8), 7.02(-8), 1.40(-7), 2.81(-7) erg/s/cc. The spiral wave leads to a shockbore, which includes the tall vertical shock front and the gas flowing up and over it The resulting surface wave crashes back onto the disk creating high-altitude shocks and vortical flows.
  • Radiative Cooling with and without Irradiation. Equatorial and side views. Maximum grain size = 1 micron.
  • Tcool=1/4. Equatorial and side view. This calculation only goes from 12 to 14 orps in high resolution.
  • Tcool=1/4. Zoom in the central region.
  • Tcool=1. Equatorial and side views. This calculation only goes from 11 to 18 orps.
  • Tcool=1. Zoom in the central region.
  • Tcool=2 (see Pickett et al. 2003). Equatorial and side views.
  • Tcool=2 (called Case 1 in ASP Conf. Series paper). Equatorial and side views.
  • DivFlux (called Case 3 in ASP Conf. Series paper). Equatorial and side views.
  • Isothermal VC (called Case 1 in SC2000 poster). Equatorial view.
  • Isothermal no VC (called Case 2 in SC2000 poster). Equatorial view.
  • Adiabatic AV on (called Case 3 in SC2000 poster). Equatorial view.
