Towards a Singularity-Proof Scheme in Numerical Relativity
Edward Seidel ; Wai-Mo Suen ;
Date 29 Oct 1992
Subject gr-qc
AbstractProgress in numerical relativity has been hindered for 30 years because of the difficulties of avoiding spacetime singularities in numerical evolution. We propose a scheme which excises a region inside an apparent horizon containing the singularity. Two major ingredients of the scheme are the use of a horizon-locking coordinate and a finite differencing which respects the causal structure of the spacetime. Encouraging results of the scheme in the spherical collapse case are given.
