Detailed Description

Boundary linear integrator for imposing non-zero Dirichlet boundary conditions, to be used in conjunction with DGDiffusionIntegrator. Specifically, given the Dirichlet data $u_D$, the linear form assembles the following integrals on the boundary:

$$\sigma ⟨u_D,(Q\mathrm{\nabla }v))\cdot n⟩+\kappa ⟨h^{-1}Q{u}_D,v⟩,$$

where Q is a scalar or matrix diffusion coefficient and v is the test function. The parameters $\sigma$ and $\kappa$ should be the same as the ones used in the DGDiffusionIntegrator.
