template<specfem::element::dimension_tag DimensionTag>
class interface_index

Index pair for coupled interface points.

This struct holds the indices of corresponding points on the self and coupled sides of an interface. It provides a unified way to access the local coordinates of the interface points for both sides, which is essential for computing fluxes, and applying coupling conditions in multi-domain simulations.

Template Parameters:

DimensionTag – Spatial dimension (dim2 or dim3)
