/*! @brief Classe Echange_externe_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 a la paroi fourni par l'utilisateur.
 *
 *      h_total  : coefficient d'echange total
 *      h_imp    : coefficient d'echange a la paroi (donnee utilisateur)
 *      e/lambda : coefficient d'echange interne
 *                 avec : lambda, conductivite dans le fluide
 *                        e = d,  en laminaire
 *                        e = d',  en turbulent
 *      (ou d' est la distance equivalente calculee lors de l'application
 *        des lois de paroi)
 *           1/h_total = (1/h_imp) + (e/lambda)
 *     Ce n'est pas la classe Echange_externe_impose qui gere le calcul
 *     de h_total. La classe fournit seulement h_imp et c'est l'evaluateur
 *     de flux diffusif qui calcule les termes e/lambda et h_total.
 *     Les classes Echange_global_impose et Echange_externe_impose ont
 *     exactement la meme interface; la classe Echange_externe_impose
 *     sert donc seulement a signaler a l'evaluateur de flux diffusif
 *     qu'il doit calculer un coefficient d'echange total.
