Detailed Description

Update the convective mass flux before the Navier Stokes equations (prediction and correction steps).

This function computes a potential $\varia$ solving the equation:

$D \left( \Delta t, \varia \right) = \divs \left( \rho \vect{u}^n\right) - \Gamma^n + \dfrac{\rho^n - \rho^{n-1}}{\Delta t}$

This potential is then used to update the mass flux as follows:

$\dot{m}^{n+\frac{1}{2}}_\ij = \dot{m}^{n}_\ij - \Delta t \grad_\fij \varia \cdot \vect{S}_\ij$
