Detailed Description

Initialize \(J\) on the first hypersurface by constraining \(\Psi_0 = 0\).

Details

This algorithm first radially evolves the \(\Psi_0 = 0\) condition, which can be converted to a second-order radial ODE for J. Then, the initial data generator performs an iterative solve for the angular coordinates necessary to ensure asymptotic flatness. The parameters for the iterative procedure are determined by options AngularCoordinateTolerance and MaxIterations.
