/*! @brief Classe Echange_externe_impose: This class represents the special case of the class
 *
 *     Echange_impose_base where the total heat exchange coefficient is computed using
 *     the wall heat exchange coefficient provided by the user.
 *
 *      h_total  : total exchange coefficient
 *      h_imp    : wall exchange coefficient (user input)
 *      e/lambda : internal exchange coefficient
 *                 where: lambda, conductivity in the fluid
 *                        e = d,  in laminar regime
 *                        e = d',  in turbulent regime
 *      (where d' is the equivalent distance computed during application
 *        of the wall laws)
 *           1/h_total = (1/h_imp) + (e/lambda)
 *     It is not the Echange_externe_impose class that manages the computation
 *     of h_total. The class only provides h_imp and it is the diffusive
 *     flux evaluator that computes the e/lambda and h_total terms.
 *     The classes Echange_global_impose and Echange_externe_impose have
 *     exactly the same interface; the Echange_externe_impose class
 *     therefore only serves to signal to the diffusive flux evaluator
 *     that it must compute a total exchange coefficient.
