Three Dimensional Numerical Relativity with a Hyperbolic Formulation
Carles Bona, Joan Masso, Edward Seidel +1
We discuss a successful three-dimensional cartesian implementation of the Bona-Massó hyperbolic formulation of the 3+1 Einstein evolution equations in numerical relativity. The num…
New Coordinate Systems for Axisymmetric Black Hole Collisions
S. R. Brandt, P. Walker, P. Anninos
We describe a numerical grid generating procedure to construct new classes of orthogonal coordinate systems that are specially adapted to binary black hole spacetimes. The new coor…
Adaptative Mesh Refinement in Numerical Relativity
Joan Masso, Edward Seidel, Paul Walker
We discuss the use of Adaptative Mesh Refinement (AMR) techniques in dynamical black hole spacetimes. We compare results between traditional fixed grid methods and a new AMR applic…
Event Horizons of Numerical Black Holes
Peter Anninos, David Bernstein, Steven Brandt +5
We have developed a powerful and efficient method for locating the event horizon of a black hole spacetime, making possible the study of the dynamics of event horizons in numerical…
