`specfem::point::edge_index`¶

template<specfem::element::dimension_tag DimensionTag> struct edge_index¶

Primary template for edge index in spectral element meshes.

Template Parameters:: DimensionTag – Spatial dimension (dim2 or dim3)

Dimension-specific Specializations¶

template<> struct edge_index<specfem::element::dimension_tag::dim2> : public specfem::data_access::Accessor<specfem::datatype::AccessorType::point, specfem::data_access::DataClassType::edge_index, specfem::element::dimension_tag::dim2, false>¶

2D edge index for spectral element edge access

Provides indexing information to locate and access data at specific points along edges in 2D spectral element meshes. Contains both element-level indices (element, edge) and local coordinate indices within the edge.

Public Functions

edge_index() = default¶: Default constructor.

inline edge_index(const int ispec_, const int iedge_, const int ipoint_, const int iz_, const int ix_, const specfem::mesh_entity::dim2::type edge_type_)¶

Constructs edge index with all indices.

Parameters:

ispec_ – Element index.
iedge_ – Edge index (0-3 for 2D quad elements).
ipoint_ – Point index along edge.
iz_ – Local z-coordinate index.
ix_ – Local x-coordinate index.
edge_type_ – Mesh entity type for the edge.

Public Members

int ispec¶: Spectral element index.

int iedge¶: Local edge index within the iterator.

int ipoint¶: Point index along the edge.

int iz¶: Local z-coordinate index within element.

int ix¶: Local x-coordinate index within element.

specfem::mesh_entity::dim2::type edge_type¶: Mesh entity type for the edge.

Public Static Attributes

static constexpr auto dimension_tag = specfem::element::dimension_tag::dim2 ¶: Dimension tag for 2D specialization.

template<> struct edge_index<specfem::element::dimension_tag::dim3> : public specfem::data_access::Accessor<specfem::datatype::AccessorType::point, specfem::data_access::DataClassType::edge_index, specfem::element::dimension_tag::dim3, false>¶

3D edge index for spectral element edge access

Provides indexing information to locate and access data at specific points along edges in 3D spectral element meshes. Contains both element-level indices (element, edge) and local coordinate indices within the edge.
