/*! @brief Classe Echange_global_impose Cette classe represente le cas particulier de la classe
 *
 *     Echange_impose_base ou l'echange de chaleur total est calcule grace au
 *     coefficient d'echange de chaleur global fourni par l'utilisateur.
 *
 *     ATTENTION, dans le cas des discretisations ou T est localisee au centre de l'element (VDF)
 *     cela correspond a la modelisation d'une paroi d'echange dont l'epaisseur s'etend jusqu'a la moitie
 *     de la premiere maille.
 *
 *      h_t   : coefficient d'echange total
 *      h_imp_: coefficient d'echange global (donnee utilisateur)
 *     On a: h_t = h_imp
 *     Les champs h_imp et T_ext sont uniformes
