I am following the process from "Nodal Discontinuous Galerkin Methods" by
Jan S. Hesthaven and Tim Warburton. It might be particular to discontinuous
galerkin to do it this way but I claim to be no expert.
Regardless, if I do the same integral in weak form it still results the
same. The equation would change to:
\int_cell phi * q = \int_cell -grad phi * a + \int_face phi *
{{a}} * normal
Would an equation so simple need stabilizing?
