Detailed Description

This function adds $ \rho \vect{u} \cdot \vect{S}_\ij$ to the mass flux $ \dot{m}_\ij $ for the segregated algorithm on the velocity components.

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

For the mass flux at the boundary we have:

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

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