/*! @brief classe Sch_CN_EX_iteratif
 *
 *      Ce schema en temps implemente quelques astuces en plus de Sch_CN_iteratif pour
 *      le stabiliser au-dela de son domaine de stabilite naturel (facsec<2).
 *
 *      Un facteur d'amortissement des iterations est defini : omega.
 *      Il ameliore la stabilite, mais deterore la qualite de la resolution :
 *      Aux petits nombres d'iterations, les derivees temporelles sont sous-estimees
 *      et les lois de conservation ne sont plus necessairement satisfaites.
 *
 *      Pour augmenter le pas de temps, les equations autres que Navier-Stokes sont resolues
 *      via le calcul de plusieurs pas de temps d'Euler explicite.
 *      A chaque iteration de Sch_CN_iteratif, les n pas de temps d'Euler explicite sont recalcules.
 *
 *      Ce schema est adapte aux cas industriels de type gros calculs hydrauliques LES avec
 *      thermique couplee a du solide
