Detailed Description

This function adds $\rho \vect{u} \cdot \vect{S}_\ij$ to the mass flux $\dot{m}_\ij$ .

For the reconstruction, $\gradt \left(\rho \vect{u} \right)$ is computed with the following approximated boundary conditions:

$\vect{A}_{\rho u} = \rho_\fib \vect{A}_u$
$\tens{B}_{\rho u} = \tens{B}_u$

For the mass flux at the boundary we have:

$\dot{m}_\ib = \left[ \rho_\fib \vect{A}_u + \rho_\fib \tens{B}_u \vect{u} + \tens{B}_u \left(\gradt \vect{u} \cdot \vect{\centi \centip}\right)\right] \cdot \vect{S}_\ij$

The last equation uses some approximations detailed in the theory guide.
