ST3D

Abstract

ST3D is a Numerical Relativity code that solves the full Einstein Equations in 3-D using a finite differencing conservative scheme. ST3D is the CRAY T3D version of H3expresso, a "concentrated" ("espresso") and fast ("express") version of a general 3-D hyperbolic code that solves the Einstein equations. The hyperbolic formulation of the Einstein equations, by using a special class of gauge choice, casts the Einstein equations into a First Order Flux Conservative Hyperbolic system and thus allows the use of advanced numerical techniques. This code is the first step in building a general relativistic 3-D code for the study of the neutron star coalescence problem.
