/*! @brief classe Pb_Multiphase Cette classe represente un probleme de thermohydraulique multiphase de type "3*N equations" :
 *
 *       - QDM_Multiphase : equations de Navier-Stokes et de continuite pour chaque phase
 *                          inconnues : v_k (vitesses par phase)
 *                          champs auxiliaires : pression p, taux de presence a_k (sum a_k = 1)
 *       - Energie_Multiphase : equations de conservation de l'energie pour chaque phase
 *                              inconnues : T_k (temperatures)
 *     schema de resolution typique :
 *       1) QDM_Multiphase -> prediction des vitesses
 *                            conservation de la masse -> Newton (etape "semi-implicite")
 *       3) Energie_Multiphase -> advection/dffusion implicite de l'energie
