Detailed Description

Manages the cached buffer data associated with a CCE worldtube and interpolates to requested time points to provide worldtube boundary data to the main evolution routines.

Details

The maintained buffer will be maintained at a length that is set by the Interpolator and the buffer_depth also passed to the constructor. A longer depth will ensure that the buffer updater is called less frequently, which is useful for slow updaters (e.g. those that perform file access). The main functionality is provided by the WorldtubeDataManager::populate_hypersurface_boundary_data() member function that handles buffer updating and boundary computation.

◆ populate_hypersurface_boundary_data()

template<typename TagList >
bool Cce::WorldtubeDataManager::populate_hypersurface_boundary_data ( const gsl::not_null< db::DataBox< TagList > * >  boundary_data_box,
const double  time 
) const
inlinenoexcept

Update the boundary_data_box entries for all tags in Tags::characteristic_worldtube_boundary_tags to the boundary data at time.

Details

First, if the stored buffer requires updating, it will be updated via the buffer_updater_ supplied in the constructor. Then, each of the spatial metric, shift, lapse, and each of their radial and time derivatives are interpolated across buffer points to the requested time value (via the Interpolator provided in the constructor). Finally, that data is supplied to the create_bondi_boundary_data(), which updates the boundary_data_box with the Bondi spin-weighted scalars determined from the interpolated Cartesian data.

Returns true if the time can be supplied from the buffer_updater_, and false otherwise. No tags are updated if false is returned.
