Accurate Evolution of Orbiting Binary Black Holes
Peter Diener, Frank Herrmann, Denis Pollney +5
We present a detailed analysis of binary black hole evolutions in the last orbit, and demonstrate consistent and convergent results for the trajectories of the individual bodies. T…
New, efficient, and accurate high order derivative and dissipation operators satisfying summation by parts, and applications in three-dimensional multi-block evolutions
Peter Diener, Ernst Nils Dorband, Erik Schnetter +1
We construct new, efficient, and accurate high-order finite differencing operators which satisfy summation by parts. Since these operators are not uniquely defined, we consider sev…
Cauchy-perturbative matching revisited: tests in spherical symmetry
Burkhard Zink, Enrique Pazos, Peter Diener +1
During the last few years progress has been made on several fronts making it possible to revisit Cauchy-perturbative matching (CPM) in numerical relativity in a more robust and acc…
