Detailed Description

Computes the analytic data for a Linearized solution to the Bondi-Sachs equations described in [7].

Details

The solution represented by this function is generated with only \((2,\pm2)\) and \((3,\pm3)\) modes, and is constructed according to the linearized solution documented in Section VI of [7]. For this solution, we impose additional restrictions that the linearized solution be asymptotically flat so that it is compatible with the gauge transformations performed in the SpECTRE regularity-preserving CCE. Using the notation of [7], we set:

\begin{align*} B_2 &= B_3 = 0\\ C_{2b} &= 3 C_{2a} / \nu^2\\ C_{3b} &= -3 i C_{3a} / \nu^3 \end{align*}

where \(C_{2a}\) and \(C_{3a}\) may be specified freely and are taken via input option InitialModes.

Compute the radial derivative of the spherical coordinate metric from the linearized Bondi-Sachs system.

Details

This function dispatches to the individual computations in this class to determine the Bondi-Sachs scalars for the linearized solution. Once the scalars are determined, the radial derivative of the metric is assembled via (note \(\beta = 0\) in this solution)

\begin{align*} \partial_r g_{a b} dx^a dx^b =& - (W + r \partial_r W - 2 r h_{A B} U^A U^B - r^2 (\partial_r h_{A B}) U^A U^B - 2 r^2 h_{A B} U^A \partial_r U^B) (dt - dr)^2 \\ &- (4 r h_{A B} U^B + 2 r^2 ((\partial_r h_{A B}) U^B + h_{AB} \partial_r U^B) ) (dt - dr) dx^A + (2 r h_{A B} + r^2 \partial_r h_{A B}) dx^A dx^B, \end{align*}

where indices with capital letters refer to angular coordinates and the angular tensors may be written in terms of spin-weighted scalars. Doing so gives the metric components,
