/*! @brief Sortie_libre_Gradient_Pression_libre_VEF
 *
 *  Cette classe derive de la classe Neumann_sortie_libre
 *
 *     Elle represente une frontiere ouverte avec condition de gradient de pression calculer.
 *     La fonction flux_impose() renvoie une valeur de pression a l'exterieur calculee a partir du gradient de pression impose
 *     et de la pression a l'interieur du domaine.
