Detailed Description

template<size_t Dim>
struct elliptic::dg::InitializeFacesAndMortars< Dim >

Initialize the geometry on faces and mortars for the elliptic DG operator.

Face normals are not yet normalized, and the face-normal magnitudes are not yet computed at all. Invoke elliptic::dg::NormalizeFaceNormals for this purpose, possibly preceded by elliptic::dg::InitializeBackground if the system has a background metric.
