摘要: (February 7, 2008)We solve the elliptic equations associated with Hamil-tonian and momentum constraints, corresponding to a systemcomposed of two black holes arbitrary linear angu-lar momentum. These new solutions are based on Kerr-Schild spacetime slicing which provides more physically re-alistic than initial data conformallyflat metric/maximal methods. The singularity/innerboundary problems circumvented by technique thatallows use an solver Cartesian grid whereno points excised, simplifying enormously numericalproblem.PACS number(s): 04.70.Bw,04.25.DmI.
