The aim of this work is the development of a code for general relativistic simulations of ideal fluids on arbitrary curved spacetimes in up to three dimensions. The numerical method is based on a High Resolution Shock Capturing (HRSC) algorithm. The HRSC method was modified in a way such that pressure and gravitational forces are computed consistently. Because of this, a higher accuracy is achieved for quasi-stationary, isentropic systems. In contrast to linearised schemes, the method is still applicable in general scenarios. The new method uses a new formulation of the general relativistic hydrodynamic evolution equations, which I developed for this purpose. The code has been tested successfully on a nonrotating and a rigidly rotating neut...
