    ifct  : numero de la fonction definissant les variables primitives 
          / number of the function defining the primitive variables
    
    SORTIES / OUTPUT
    vprim     : variables primitives / primitive variables
 modele bifluide : densite,vitesse suivant x,y,z, pression
 / two-fluid model: density, velocity along x,y,z, pressure
 modele St-Venant: hauteur d eau,vitesse suivant x,y
 /St-Venant model: water height, velocity along x,y
