Update the convective mass flux before the Navier Stokes equations (prediction and correction steps).
This function computes a potential  solving the equation:
 solving the equation: 
![\[ D \left( \Delta t, \varia \right) = \divs \left( \rho \vect{u}^n\right) - \Gamma^n + \dfrac{\rho^n - \rho^{n-1}}{\Delta t} \]](form_283.png) 
This potential is then used to update the mass flux as follows:
![\[ \dot{m}^{n+\frac{1}{2}}_\ij = \dot{m}^{n}_\ij - \Delta t \grad_\fij \varia \cdot \vect{S}_\ij \]](form_284.png)
