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:

\[ \sigma \langle u_D, (Q \nabla v)) \cdot n \rangle + \kappa \langle {h^{-1} Q} u_D, v \rangle, \]

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.
