/*! @brief classe Navier_Stokes_Fluide_Dilatable_base Cette classe basse porte les termes de l'equation de la dynamique
 *
 *     pour un fluide sans modelisation de la turbulence.
 *     On suppose l'hypothese de fluide dilatable.
 *     Sous ces hypotheses, on utilise la forme suivante des equations de
 *     Navier_Stokes:
 *        DU/dt = div(terme visqueux) - gradP/rho + sources/rho
 *        div U = W
 *     avec DU/dt : derivee particulaire de la vitesse
 *          rho   : masse volumique
 *     Rq : l'implementation de la classe permet bien sur de negliger
 *          certains termes de l'equation (le terme visqueux, le terme
 *          convectif, tel ou tel terme source).
 *     L'inconnue est le champ de vitesse.
