/*! @brief Classe Pb_Phase_field Cette classe represente un probleme d'hydraulique avec transport
 *
 *     d'un ou plusieurs constituants:
 *        - Equations de Navier_Stokes en regime laminaire
 *          pour un fluide incompressible
 *        - Equations de convection-diffusion en regime laminaire
 *          En fait si on transporte plusieurs constituants on utilisera une
 *          seule equation de convection-diffusion avec une inconnue vectorielle.
 *          En general, on couple les 2 equations par l'intermediaire du terme
 *          source des forces de volume de Navier_Stokes dans lequel on prend
 *          en compte de petites variations de la masse volumique en fonction
 *          du ou des constituants
