/*! @brief classe Sortie_libre_pression_moyenne_imposee Cette classe derive de Neumann_sortie_libre
 *
 *     Elle represente une frontiere ouverte avec condition de niveau moyen de pression impose (un gradient peut donc apparaitre).
 *     L'objet de type Champ_bord le_champ_bord contient la pression et la fonction flux_impose() renvoie les valeurs de cette pression.
 *     champ_ext contient une valeur de la vitesse du fluide a l'exterieur accessible par la methode val_ext()
