Le but de ce sous-programme est principalement de calculer le flux de masse aux
faces. Il prend une variable vectorielle associ\'ee au centre des cellules
(g\'en\'eralement la vitesse), la projette aux faces en la multipliant par la
masse volumique, et la multiplie scalairement par le vecteur surface.
Plus g\'en\'eralement, \fort{inimas} est aussi appel\'e comme premi\`ere \'etape 
du calcul d'une divergence (terme en $\dive(\rho\tens{R})$ en
$R_{ij}-\varepsilon$, filtre Rhie \& Chow, ...).
