Abstract
The main features of a three dimensional, high--resolution special relativistic hydro code based on relativistic Riemann solvers are described. The capabilities and performance of the code are discussed. In particular, we present the results of extensive test calculations which demonstrate that the code can accurately and efficiently handle strong shocks in three spatial dimensions. Results of the performance of the code on single and multi-processor machines are given. Simulations (in double precision) with 7 10 6 computational cells require less than 1 Gb of RAM memory and ß 7 10 \Gamma5 CPU seconds per zone and time step (on a SCI Cray--Origin 2000 with a R10000 processor) . Currently, a version of the numerical code is under development, which is suited for massively parallel computers with distributed memory architecture (like, e.g., Cray T3E). Subject headings: galaxies: jets --- hydrodynamics --- methods: numerical --- relativity 1. Introduction Numerical relativistic hyd...
