DataBox tags related to elliptic discontinuous Galerkin schemes. More...

## Classes

struct  ElementSize
A measure of element size perpendicular to an element face. Used to compute the penalty (see elliptic::dg::penalty). More...

struct  Massive
Whether or not to multiply the DG operator with the mass matrix. Massive DG operators can be easier to solve because they are symmetric, or at least closer to symmetry. More...

struct  MortarData
Holds elliptic::dg::MortarData, i.e. boundary data on both sides of a mortar. More...

struct  NormalDotFluxForJump
The quantity $$n_i F^i_u(n_j F^j_v(u))$$ where $$F^i$$ is the system flux for primal variables $$u$$ and auxiliary variables $$v$$, and $$n_i$$ is the face normal. This quantity is projected to mortars to compute the jump term of the numerical flux. More...

struct  PenaltyParameter
The prefactor to the penalty term of the numerical flux. More...

struct  PerpendicularNumPoints
Number of grid points perpendicular to an element face. Used to compute the penalty (see elliptic::dg::penalty). More...
