Numerical simulations of matter flows evolving in the presence of strong (and dynamic) gravitational fields are a highly complex problem. In order to simplify the complexity of the gravitational field equations of general relativity, Wilson and coworkers proposed an approximation scheme, where the 3-metric γij is chosen to be conformally fiat, which reduces the Einstein equations to a set of 5 coupled elliptic equations. In this paper we present an axisymmetric general relativistic hydrodynamic code which is based upon this approach, and utilizes high-resolution shock-capturing schemes to solve the hydrodynamic equations. We report on preliminary applications of the code to rotating neutron stars and supernova core collapse in axisymmetry. These results demonstrate the feasibility of the code to handle a variety of relativistic astrophysical situations. The code will be used in the near future to obtain information about gravitational radiation from rotating gravitational collapse.
