Detailed Description

BilinearFormIntegrator for the high-order extension of shifted boundary method. A(u, w) = -<nabla u.n, w> -<u + nabla u.d + h.o.t, nabla w.n> -<alpha h^{-1} (u + nabla u.d + h.o.t), w + nabla w.d + h.o.t> where h.o.t include higher-order derivatives (nabla^k u) due to Taylor expansion. Since this interior face integrator is applied to the surrogate boundary (see marking.hpp for notes on how the surrogate faces are determined and elements are marked), this integrator adds contribution to only the element that is adjacent to that face (Trans.Elem1 or Trans.Elem2) and is part of the surrogate domain.
