Black hole evolution with the BSSN system by pseudospectral methods
Black hole evolution with the BSSN system by pseudospectral methods
We present a new pseudospectral code for the simulation of evolution systems that are second order in space. We test this code by evolving a nonlinear scalar wave equation. These nonlinear waves can be stably evolved using very simple constant or radiative boundary conditions, which we show to be well-posed …
