Authors: Sascha Husa, Jose A. Gonzalez, Mark Hannam, Bernd Bruegmann, Ulrich Sperhake Date: 5 Jun 2007 Abstract: We describe a modification of a fourth-order accurate ‘moving puncture’ evolution code, where by replacing spatial fourth-order accurate differencing operators in the bulk of the grid by a specific choice of sixth-order accurate stencils we gain significant improvements in accuracy. We illustrate the performance of the modified algorithm with an equal-mass simulation covering nine orbits. |
