Detailed Description

template<typename Metavariables>
struct Initialization::Actions::DiscontinuousGalerkin< Metavariables >

Initialize items related to the discontinuous Galerkin method.

Uses:

  • DataBox:
    • Tags::Element<Dim>
    • Tags::Mesh<Dim>
    • Tags::Next<temporal_id_tag>
    • Tags::Interface<Tags::InternalDirections<Dim>, Tags::Mesh<Dim - 1>>

DataBox changes:

  • Adds:
    • Tags::Interface<Tags::InternalDirections<Dim>, normal_dot_fluxes_tag>
    • Tags::Interface<Tags::BoundaryDirectionsInterior<Dim>, normal_dot_fluxes_tag>
    • Tags::Interface<Tags::BoundaryDirectionsExterior<Dim>, normal_dot_fluxes_tag>
  • Removes: nothing
  • Modifies: nothing
Note
This action relies on the SetupDataBox aggregated initialization mechanism, so Actions::SetupDataBox must be present in the Initialization phase action list prior to this action.
