Phys. Rev. Lett. 85, 5500–5503 (2000)Solving the Initial Value Problem of Two Black HolesReceived 31 August 2000; published in the issue dated 25 December 2000 We solve the elliptic equations associated with the Hamiltonian and momentum constraints, corresponding to a system composed of two black holes with arbitrary linear and angular momentum. These new solutions are based on a Kerr-Schild spacetime slicing which provides more physically realistic solutions than the initial data based on conformally flat metric/maximal slicing methods. The singularity/inner boundary problems are circumvented by a new technique that allows the use of an elliptic solver on a Cartesian grid where no points are excised, simplifying enormously the numerical problem. © 2000 The American Physical Society URL:
