Detailed Description

Initialize \(J\) on the first hypersurface to be vanishing, finding the appropriate angular coordinates to be continuous with the provided worldtube boundary data.

Details

Internally, this performs an iterative solve for the angular coordinates necessary to give rise to a vanishing gauge-transformed J on the worldtube boundary. The parameters for the iterative procedure are determined by options ZeroNonSmooth::AngularCoordinateTolerance and ZeroNonSmooth::MaxIterations. The resulting J will necessarily have vanishing first radial derivative, and so will typically not be smooth (only continuous) with the provided Cauchy data at the worldtube boundary.
