Spin Dependence in Computational Black Hole Data
Scott H. Hawley, Michael J. Vitalo, Richard A. Matzner
We have implemented a parallel multigrid solver, to solve the initial data problem for 3+1 General Relativity. This involves solution of elliptic equations derived from the Hamilto…
Dynamical evolution of quasi-circular binary black hole data
Miguel Alcubierre, Bernd Bruegmann, Peter Diener +8
We study the fully nonlinear dynamical evolution of binary black hole data, whose orbital parameters are specified via the effective potential method for determining quasi-circular…
Evolutions in 3D numerical relativity using fixed mesh refinement
Erik Schnetter, Scott H. Hawley, Ian Hawke
We present results of 3D numerical simulations using a finite difference code featuring fixed mesh refinement (FMR), in which a subset of the computational domain is refined in spa…
Tips for implementing multigrid methods on domains containing holes
Scott H. Hawley, Richard A. Matzner
As part of our development of a computer code to perform 3D `constrained evolution' of Einstein's equations in 3+1 form, we discuss issues regarding the efficient solution of ellip…
Toward standard testbeds for numerical relativity
Miguel Alcubierre, Gabrielle Allen, Carles Bona +18
In recent years, many different numerical evolution schemes for Einstein's equations have been proposed to address stability and accuracy problems that have plagued the numerical r…
Numerical evidence for `multi-scalar stars'
Scott H. Hawley, Matthew W. Choptuik
We present a class of general relativistic soliton-like solutions composed of multiple minimally coupled, massive, real scalar fields which interact only through the gravitational…
