Detailed Description

template<typename System, typename Metavariables, bool UsingRuntimeId>
struct evolution::dg::BackgroundGrVars< System, Metavariables, UsingRuntimeId >

Allocate or assign background general relativity quantities needed for evolution systems run on a curved spacetime without solving Einstein equations (e.g. ValenciaDivclean, ForceFree).

Warning: This mutator assumes that the GR analytic data or solution specifying background spacetime metric is time-independent.

The documentation for this struct was generated from the following file:
