Detailed Description

Abstract base class for an initial hypersurface data generator for Cce, when the partially flat Bondi-like coordinates are not evolved.

Details

The functions that are required to be overriden in the derived classes are:

• InitializeJ::get_clone(): should return a std::unique_ptr<InitializeJ<false>> with cloned state.
• InitializeJ::operator() const: should take as arguments, first a set of gsl::not_null pointers represented by mutate_tags, followed by a set of const references to quantities represented by argument_tags.

  Note

  The InitializeJ::operator() should be const, and therefore not alter the internal state of the generator. This is compatible with all known use-cases and permits the InitializeJ generator to be placed in the GlobalCache.

du_dr_j_interpolator()

inlinevirtual

The interpolator this generator wants used to build the worldtube boundary value of \(\partial_u \partial_r J\), or nullptr to use the evolution's H5Interpolator.

Details

That boundary value is consumed by the initial data alone, so a generator is free to choose its own time-interpolation order for it without affecting the evolution.

Reimplemented in Cce::InitializeJ::CauchySecondOrder.
