Detailed Description

template<typename System, typename BackgroundTag, typename OptionsGroup, bool FromInitialDomain = true>
struct elliptic::dg::subdomain_operator::Actions::InitializeSubdomain< System, BackgroundTag, OptionsGroup, FromInitialDomain >

Initialize the geometry for the DG subdomain operator.

Initializes tags that define the geometry of overlap regions with neighboring elements. The data needs to be updated if the geometry of neighboring elements changes.

Note that the geometry depends on the system and on the choice of background through the normalization of face normals, which involves a metric.

The FromInitialDomain template parameter controls how the next-to-nearest-neighbor information is acquired:

• If FromInitialDomain = true, uses the initial parameters from the input file. This can be used at the beginning of a simulation or if the domain never changes (no AMR).
• If FromInitialDomain = false, uses the mesh, element, and neighbor meshes of each neighbor. This typically requires communication to exchange this data between neighbors each time the domain changes, e.g. with AMR.

DataBox:

• Uses:
  • BackgroundTag
  • domain::Tags::Element<Dim>
  • If FromInitialDomain = true:
    • domain::Tags::InitialExtents<Dim>
    • domain::Tags::InitialRefinementLevels<Dim>
    • elliptic::dg::Tags::Quadrature
  • If FromInitialDomain = false:
    • Overlaps<domain::Tags::Mesh<Dim>>
    • Overlaps<domain::Tags::Element<Dim>>
    • Overlaps<domain::Tags::NeighborMesh<Dim>>
  • domain::Tags::Domain<Dim>
  • domain::Tags::FunctionsOfTime
  • LinearSolver::Schwarz::Tags::MaxOverlap<OptionsGroup>
• Adds: Many tags prefixed with LinearSolver::Schwarz::Tags::Overlaps. See elliptic::dg::Actions::InitializeDomain and elliptic::dg::Actions::initialize_operator for a complete list.
