Detailed Description

template<size_t Dim, typename System, typename DerivedBoundaryConditionsList>
struct evolution::dg::Initialization::BoundaryEvolvedVariables< Dim, System, DerivedBoundaryConditionsList >

Allocates and initializes the system's boundary-evolved variables (the Tags::BoundaryVariables entry of the list-valued System::variables_tag) on each opting external face.

Iterates the element's external boundaries and gives each face whose boundary condition opts in (declares the evolves_boundary_variables marker) a face-sized entry in the BoundaryVariables storage. Each Tags::BoundaryValue<Source> is initialized by projecting its interior Source from the volume variables to the face. Interior and non-opting faces get no entry.

Runs after the domain and the initial data are set, and before Initialization::TimeStepperHistory, which sizes the Tags::dt twin of the storage from the per-face storage initialized here.

Template Parameters

Dim	the spatial dimension
System	the evolution system (supplies variables_tag)
DerivedBoundaryConditionsList	the concrete boundary condition types; it must contain every type that can appear on an external boundary
