Impact of densitized lapse slicings on evolutions of a wobbling black hole
U. Sperhake, K. L. Smith, B. Kelly +2
We present long-term stable and second-order convergent evolutions of an excised wobbling black hole. Our results clearly demonstrate that the use of a densitized lapse function ex…
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…
Moving black holes via singularity excision
D. Shoemaker, K. Smith, U. Sperhake +3
We present a singularity excision algorithm appropriate for numerical simulations of black holes moving throughout the computational domain. The method is an extension of the excis…
