Detailed Description

A boundary data manager that constructs the desired boundary data into the Variables from the data provided by the analytic solution.

populate_du_dr_j()

void Cce::AnalyticBoundaryDataManager::populate_du_dr_j	(	gsl::not_null< Variables< Tags::characteristic_worldtube_boundary_tags< Tags::BoundaryValue > > * >	boundary_data_variables,
		double	time ) const

Update the Du<Dr<BondiJ>> entry of boundary_data_variables at time if an interpolator was given with set_du_dr_j_interpolator.

Details

Samples Dr<BondiJ> from the analytic solution at 2 * interpolator->required_number_of_points_before_and_after() times spaced by Cce::OptionTags::DuDrJStencilStep and centered on time, and differentiates it with the interpolator.

populate_hypersurface_boundary_data()

bool Cce::AnalyticBoundaryDataManager::populate_hypersurface_boundary_data	(	gsl::not_null< Variables< Tags::characteristic_worldtube_boundary_tags< Tags::BoundaryValue > > * >	boundary_data_variables,
		double	time ) const

Update the boundary_data_variables entries for all tags in Tags::characteristic_worldtube_boundary_tags except Du<Dr<BondiJ>> (see populate_du_dr_j) to the boundary data from the analytic solution at time.

Details

This class retrieves metric boundary data from the Cce::Solutions::WorldtubeData derived class that represents an analytic solution, then dispatches to Cce::create_bondi_boundary_data() to construct the Bondi values into the provided Variables
