Detailed Description

template<typename InterpolationTargetTag>
struct intrp::callbacks::DumpBondiSachsOnWorldtube< InterpolationTargetTag >

Post interpolation callback that dumps metric data in Bondi-Sachs form on a number of extraction radii given by the intrp::TargetPoints::Sphere target.

To use this callback, the target must be the intrp::TargetPoints::Sphere target in the inertial frame. This callback also expects that the GH source vars on each of the target spheres are:

• gr::Tags::SpacetimeMetric
• gh::Tags::Pi
• gh::Tags::Phi

This callback will write a new H5 file for each extraction radius in the Sphere target. The name of this file will be a file prefix specified by the Cce::Tags::FilePrefix prepended onto CceRXXXX.h5 where the XXXX is the zero-padded extraction radius rounded to the nearest integer. The quantities that will be written are

• Cce::Tags::BondiBeta
• Cce::Tags::Dr<Cce::Tags::BondiJ>
• Cce::Tags::Du<Cce::Tags::BondiR>
• Cce::Tags::BondiH
• Cce::Tags::BondiJ
• Cce::Tags::BondiQ
• Cce::Tags::BondiR
• Cce::Tags::BondiU
• Cce::Tags::BondiW

Note

For all real quantities (Beta, DuR, R, W) we omit writing the negative m modes, and the imaginary part of the m = 0 mode.
