  We describe a newly developed hydrodynamic code for studying accretion disk
processes. The numerical method uses a finite volume, nonlinear, Total
Variation Diminishing (TVD) scheme to capture shocks and control spurious
oscillations. It is second-order accurate in time and space and makes use of a
FARGO-type algorithm to alleviate Courant-Friedrichs-Lewy time step
restrictions imposed by the rapidly rotating inner disk region. OpenMP
directives are implemented enabling faster computations on shared-memory,
multi-processor machines. The resulting code is simple, fast and memory
efficient. We discuss the relevant details of the numerical method and provide
results of the code's performance on standard test problems. We also include a
detailed examination of the code's performance on planetary disk-planet
interactions. We show that the results produced on the standard problem setup
are consistent with a wide variety of other codes.
