Detailed Description

Integrator for the DG form:

- < {(Q grad(u)).n}, [v] > + sigma < [u], {(Q grad(v)).n} >
+ kappa < {h^{-1} Q} [u], [v] >

where Q is a scalar or matrix diffusion coefficient and u, v are the trial and test spaces, respectively. The parameters sigma and kappa determine the DG method to be used (when this integrator is added to the "broken" DiffusionIntegrator): sigma = -1, kappa >= kappa0: symm. interior penalty (IP or SIPG) method, sigma = +1, kappa > 0: non-symmetric interior penalty (NIPG) method, sigma = +1, kappa = 0: the method of Baumann and Oden.
