NavierStokesHDGOutflowBC

This class implements an outflow boundary condition for use with the hybridized kernel NavierStokesHDGKernel. The condition imposed is

npμun=0\vec{n}p -\mu\nabla\vec{u}\cdot{n} = \vec{0}

where n\vec{n} is the outward-facing normal on the boundary, pp is the pressure, ν\nu is the kinematic viscosity, and u\vec{u} is the velocity.
